Amazon EMR Release 5.23.0
The following applications are supported in this release: Flink, Ganglia, Hadoop, HBase, HCatalog, Hive, Hue, JupyterHub, Livy, Mahout, MXNet, Oozie, Phoenix, Pig, Presto, Spark, Sqoop, TensorFlow, Tez, Zeppelin, and ZooKeeper.
The diagram below depicts the application versions available in this release of Amazon EMR and the application versions in the preceding four Amazon EMR releases.
For a comprehensive history of application versions for each release of Amazon EMR, see the following diagrams:
The following release notes include information for Amazon EMR release version 5.23.0. Changes are relative to 5.22.0.
Initial release date: April 01, 2019
Last updated date: April 30, 2019
Upgrades
-
AWS SDK for Java 1.11.519
New Features
-
(April 30, 2019) With Amazon EMR 5.23.0 and later, you can launch a cluster with three master nodes to support high availability of applications like YARN Resource Manager, HDFS Name Node, Spark, Hive, and Ganglia. The master node is no longer a potential single point of failure with this feature. If one of the master nodes fails, Amazon EMR automatically fails over to a standby master node and replaces the failed master node with a new one with the same configuration and bootstrap actions. For more information, see Plan and Configure Master Nodes.
Known Issues
-
Tez UI
Tez UI does not work on an EMR cluster with multiple master nodes.
-
Hue (Fixed in Amazon EMR release version 5.24.0)
-
Hue running on Amazon EMR does not support Solr. Beginning with Amazon EMR release version 5.20.0, a misconfiguration issue causes Solr to be enabled and a harmless error message to appear similar to the following:
Solr server could not be contacted properly: HTTPConnectionPool('host=ip-xx-xx-xx-xx.ec2.internal', port=1978): Max retries exceeded with url: /solr/admin/info/system?user.name=hue&doAs=administrator&wt=json (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',))To prevent the Solr error message from appearing:
-
Connect to the master node command line using SSH.
-
Use a text editor to open the
hue.inifile. For example:sudo vim /etc/hue/conf/hue.ini -
Search for the term "appblacklist" and modify the line to the following:
appblacklist = search -
Save your changes and restart Hue as shown in the following example:
sudo stop hue; sudo start hue

Amazon EMR Release 5.22.0
The following applications are supported in this release: Flink, Ganglia, Hadoop, HBase, HCatalog, Hive, Hue, JupyterHub, Livy, Mahout, MXNet, Oozie, Phoenix, Pig, Presto, Spark, Sqoop, TensorFlow, Tez, Zeppelin, and ZooKeeper.
The diagram below depicts the application versions available in this release of Amazon EMR and the application versions in the preceding four Amazon EMR releases.
For a comprehensive history of application versions for each release of Amazon EMR, see the following diagrams:
The following release notes include information for Amazon EMR release version 5.22.0. Changes are relative to 5.21.0.
Important
Beginning with Amazon EMR release version 5.22.0, Amazon EMR uses AWS Signature Version 4 exclusively to authenticate requests to Amazon S3. Earlier Amazon EMR release versions use AWS Signature Version 2 in some cases, unless the release notes indicate that Signature Version 4 is used exclusively. For more information, see Authenticating Requests (AWS Signature Version 4) and Authenticating Requests (AWS Signature Version 2) in the Amazon Simple Storage Service Developer Guide.
Initial release date: March 20, 2019
Upgrades
-
Flink 1.7.1
-
HBase 1.4.9
-
Oozie 5.1.0
-
Phoenix 4.14.1
-
Zeppelin 0.8.1
-
Connectors and drivers:
-
DynamoDB Connector 4.8.0
-
MariaDB Connector 2.2.6
-
Amazon Redshift JDBC Driver 1.2.20.1043
-
New Features
-
Modified the default EBS configuration for EC2 instance types with EBS-only storage. When you create a cluster using Amazon EMR release version 5.22.0 and later, the default amount of EBS storage increases based on the size of the instance. In addition, we split increased storage across multiple volumes, giving increased IOPS performance. If you want to use a different EBS instance storage configuration, you can specify it when you create an EMR cluster or add nodes to an existing cluster. For more information about the amount of storage and number of volumes allocated by default for each instance type, see Default EBS Storage for Instances in the Amazon EMR Management Guide.
Changes, Enhancements, and Resolved Issues
-
Spark
-
Introduced a new configuration property for Spark on YARN,
spark.yarn.executor.memoryOverheadFactor. The value of this property is a scale factor that sets the value of memory overhead to a percentage of executor memory, with a minimum of 384 MB. If memory overhead is set explicitly usingspark.yarn.executor.memoryOverhead, this property has no effect. The default value is0.1875, representing 18.75%. This default for Amazon EMR leaves more space in YARN containers for executor memory overhead than the 10% default set internally by Spark. The Amazon EMR default of 18.75% empirically showed fewer memory-related failures in TPC-DS benchmarks. -
Backported SPARK-26316 to improve performance.
-
Known Issues
-
Hue (Fixed in Amazon EMR release version 5.24.0)
-
Hue running on Amazon EMR does not support Solr. Beginning with Amazon EMR release version 5.20.0, a misconfiguration issue causes Solr to be enabled and a harmless error message to appear similar to the following:
Solr server could not be contacted properly: HTTPConnectionPool('host=ip-xx-xx-xx-xx.ec2.internal', port=1978): Max retries exceeded with url: /solr/admin/info/system?user.name=hue&doAs=administrator&wt=json (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',))To prevent the Solr error message from appearing:
-
Connect to the master node command line using SSH.
-
Use a text editor to open the
hue.inifile. For example:sudo vim /etc/hue/conf/hue.ini -
Search for the term "appblacklist" and modify the line to the following:
appblacklist = search -
Save your changes and restart Hue as shown in the following example:
sudo stop hue; sudo start hue
-

Tez
-
This issue was fixed in Amazon EMR 5.22.0.
When you connect to the Tez UI at http://
MasterDNS:8080/tez-ui through an SSH connection to the cluster master node, the error "Adapter operation failed - Timeline server (ATS) is out of reach. Either it is down, or CORS is not enabled" appears, or tasks unexpectedly show N/A.This is caused by the Tez UI making requests to the YARN Timeline Server using
localhostrather than the host name of the master node. As a workaround, a script is available to run as a bootstrap action or step. The script updates the host name in the Tezconfigs.envfile. For more information and the location of the script, see the Bootstrap Instructions.

The following release notes include information for Amazon EMR release version 5.20.0. Changes are relative to 5.19.0.
Initial release date: December 18, 2018
Last updated date: January 22, 2019
Upgrades
-
Flink 1.6.2
-
HBase 1.4.8
-
Hive 2.3.4
-
Hue 4.3.0
-
MXNet 1.3.1
-
Presto 0.214
-
Spark 2.4.0
-
TensorFlow 1.12.0
-
Tez 0.9.1
-
AWS SDK for Java 1.11.461
New Features
-
(January 22, 2019) Kerberos in Amazon EMR has been improved to support authenticating principals from an external KDC. This centralizes principal management because multiple clusters can share a single, external KDC. In addition, the external KDC can have a cross-realm trust with an Active Directory domain. This allows all clusters to authenticate principals from Active Directory. For more information, see Use Kerberos Authentication in the Amazon EMR Management Guide.
Changes, Enhancements, and Resolved Issues
-
Default Amazon Linux AMI for Amazon EMR
-
Python3 package was upgraded from python 3.4 to 3.6.
-
-
The EMRFS S3-optimized committer
-
The EMRFS S3-optimized committer is now enabled by default, which improves write performance. For more information, see Using the EMRFS S3-optimized Committer.
-
-
Hive
-
Backported HIVE-16686.
-
-
Glue with Spark and Hive
-
In EMR 5.20.0 or later, parallel partition pruning is enabled automatically for Spark and Hive when AWS Glue Data Catalog is used as the metastore. This change significantly reduces query planning time by executing multiple requests in parallel to retrieve partitions. The total number of segments that can be executed concurrently range between 1 and 10. The default value is 5, which is a recommended setting. You can change it by specifying the property
aws.glue.partition.num.segmentsinhive-siteconfiguration classification. If throttling occurs, you can turn off the feature by changing the value to 1. For more information, see AWS Glue Segment Structure.
-
Known Issues
-
Hue (Fixed in Amazon EMR release version 5.24.0)
-
Hue running on Amazon EMR does not support Solr. Beginning with Amazon EMR release version 5.20.0, a misconfiguration issue causes Solr to be enabled and a harmless error message to appear similar to the following:
Solr server could not be contacted properly: HTTPConnectionPool('host=ip-xx-xx-xx-xx.ec2.internal', port=1978): Max retries exceeded with url: /solr/admin/info/system?user.name=hue&doAs=administrator&wt=json (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',))To prevent the Solr error message from appearing:
-
Connect to the master node command line using SSH.
-
Use a text editor to open the
hue.inifile. For example:sudo vim /etc/hue/conf/hue.ini -
Search for the term "appblacklist" and modify the line to the following:
appblacklist = search -
Save your changes and restart Hue as shown in the following example:
sudo stop hue; sudo start hue
-
-
-
Tez
-
This issue was fixed in Amazon EMR 5.22.0.
When you connect to the Tez UI at http://
MasterDNS:8080/tez-ui through an SSH connection to the cluster master node, the error "Adapter operation failed - Timeline server (ATS) is out of reach. Either it is down, or CORS is not enabled" appears, or tasks unexpectedly show N/A.This is caused by the Tez UI making requests to the YARN Timeline Server using
localhostrather than the host name of the master node. As a workaround, a script is available to run as a bootstrap action or step. The script updates the host name in the Tezconfigs.envfile. For more information and the location of the script, see the Bootstrap Instructions.

Known Issues
-
When you create a kerberized cluster with Livy installed, Livy fails with an error that simple authentication is not enabled. Rebooting the Livy server resolves the issue. As a workaround, add a step during cluster creation that runs
sudo restart livy-serveron the master node. -
If you use a custom Amazon Linux AMI based on an Amazon Linux AMI with a creation date of 2018-08-11, the Oozie server fails to start. If you use Oozie, create a custom AMI based on an Amazon Linux AMI ID with a different creation date. You can use the following AWS CLI command to return a list of Image IDs for all HVM Amazon Linux AMIs with a 2018.03 version, along with the release date, so that you can choose an appropriate Amazon Linux AMI as your base. Replace MyRegion with your region identifier, such as us-west-2.
aws ec2 --regionMyRegiondescribe-images --owner amazon --query 'Images[?Name!=`null`]|[?starts_with(Name, `amzn-ami-hvm-2018.03`) == `true`].[CreationDate,ImageId,Name]' --output text | sort -rk1

-
-
Spark
-
Apache Spark version 2.3.1, available beginning with Amazon EMR release version 5.16.0, addresses CVE-2018-8024 and CVE-2018-1334. We recommend that you migrate earlier versions of Spark to Spark version 2.3.1 or later.
-
Known Issues
-
This release version does not support the c1.medium or m1.small instance types. Clusters using either of these instance types fail to start. As a workaround, specify a different instance type or use a different release version.
-
When you create a kerberized cluster with Livy installed, Livy fails with an error that simple authentication is not enabled. Rebooting the Livy server resolves the issue. As a workaround, add a step during cluster creation that runs
sudo restart livy-serveron the master node.

Release 5.14.0 Application Versions
The following applications are supported in this release: Flink, Ganglia, Hadoop, HBase, HCatalog, Hive, Hue, JupyterHub, Livy, Mahout, MXNet, Oozie, Phoenix, Pig, Presto, Spark, Sqoop, Tez, Zeppelin, and ZooKeeper.
The diagram below depicts the application versions available in this release of Amazon EMR and the application versions in the preceding four Amazon EMR releases.
For a comprehensive history of application versions for each release of Amazon EMR, see the following diagrams:
The following release notes include information for Amazon EMR release version 5.14.0. Changes are relative to 5.13.0.
Initial release date: June 4, 2018
Upgrades
-
Upgraded Apache Flink to 1.4.2
-
Upgraded Apache MXnet to 1.1.0
-
Upgraded Apache Sqoop to 1.4.7
New Features
-
Added JupyterHub support. For more information, see JupyterHub.
Changes, Enhancements, and Resolved Issues
-
EMRFS
-
The userAgent string in requests to Amazon S3 has been updated to contain the user and group information of the invoking principal. This can be used with AWS CloudTrail logs for more comprehensive request tracking.
-
-
HBase
-
Included HBASE-20447, which addresses an issue that could cause cache issues, especially with split regions.
-
-
MXnet
-
Added OpenCV libraries.
-
-
Spark
-
When Spark writes Parquet files to an Amazon S3 location using EMRFS, the FileOutputCommitter algorithm has been updated to use version 2 instead of version 1. This reduces the number of renames, which improves application performance. This change does not affect:
-
Applications other than Spark.
-
Applications that write to other file systems, such as HDFS (which still use version 1 of FileOutputCommitter).
-
Applications that use other output formats, such as text or csv, that already use EMRFS direct write.
-
-
Known Issues
-
JupyterHub
-
Using configuration classifications to set up JupyterHub and individual Jupyter notebooks when you create a cluster is not supported. Edit the jupyterhub_config.py file and jupyter_notebook_config.py files for each user manually. For more information, see Configuring JupyterHub.
-
JupyterHub fails to start on clusters within a private subnet, failing with the message
Error: ENOENT: no such file or directory, open '/etc/jupyter/conf/server.crt'. This is caused by an error in the script that generates self-signed certificates. Use the following workaround to generate self-signed certificates. All commands are executed while connected to the master node.-
Copy the certificate generation script from the container to the master node:
sudo docker cp jupyterhub:/tmp/gen_self_signed_cert.sh ./ -
Use a text editor to change line 23 to change public hostname to local hostname as shown below:
localhostname=$(curl -s $EC2_METADATA_SERVICE_URI/local-hostname) -
Run the script to generate self-signed certificates:
sudo bash ./gen_self_signed_cert.sh -
Move the certificate files that the script generates to the
/etc/jupyter/conf/directory:sudo mv /tmp/server.crt /tmp/server.key /etc/jupyter/conf/
You can
tailthejupyter.logfile to verify that JupyterHub restarted and is returning a 200 response code. For example:tail -f /var/log/jupyter/jupyter.logThis should return a response similar to the following:
# [I 2018-06-14 18:56:51.356 JupyterHub app:1581] JupyterHub is now running at https://:9443/ # 19:01:51.359 - info: [ConfigProxy] 200 GET /api/routes -
