Troubleshooting Errors in AWS Glue

If you encounter errors in AWS Glue, use the following solutions to help you find the source of the problems and fix them.

Note

The AWS Glue GitHub repository contains additional troubleshooting guidance in AWS Glue Frequently Asked Questions.

Error: Resource Unavailable

If AWS Glue returns a resource unavailable message, you can view error messages or logs to help you learn more about the issue. The following tasks describe general methods for troubleshooting.

  • For any connections and development endpoints that you use, check that your cluster has not run out of elastic network interfaces.

Error: Could Not Find S3 Endpoint or NAT Gateway for subnetId in VPC

Check the subnet ID and VPC ID in the message to help you diagnose the issue.

  • Check that you have an Amazon S3 VPC endpoint set up, which is required with AWS Glue. In addition, check your NAT gateway if that's part of your configuration. For more information, see Amazon VPC Endpoints for Amazon S3.

Error: Inbound Rule in Security Group Required

At least one security group must open all ingress ports. To limit traffic, the source security group in your inbound rule can be restricted to the same security group.

Error: Outbound Rule in Security Group Required

At least one security group must open all egress ports. To limit traffic, the source security group in your outbound rule can be restricted to the same security group.

Error: Custom DNS Resolution Failures

When using a custom DNS for internet name resolution, both forward DNS lookup and reverse DNS lookup must be implemented. Otherwise, you might receive errors similar to: Reverse dns resolution of ip failure or Dns resolution of dns failed. If AWS Glue returns a message, you can view error messages or logs to help you learn more about the issue. The following tasks describe general methods for troubleshooting.

  • A custom DNS configuration without reverse lookup can cause AWS Glue to fail. Check your DNS configuration. If you are using Route 53 or Microsoft Active Directory, make sure that there are forward and reverse lookups. For more information, see Setting Up DNS in Your VPC.

Error: Job run failed because the role passed should be given assume role permissions for the AWS Glue Service

The user who defines a job must have permission for iam:PassRole for AWS Glue.

Error: DescribeVpcEndpoints Action Is Unauthorized. Unable to Validate VPC ID vpc-id

  • Check the policy passed to AWS Glue for the ec2:DescribeVpcEndpoints permission.

Error: DescribeRouteTables Action Is Unauthorized. Unable to Validate Subnet Id: subnet-id in VPC id: vpc-id

  • Check the policy passed to AWS Glue for the ec2:DescribeRouteTables permission.

Error: Failed to Call ec2:DescribeSubnets

  • Check the policy passed to AWS Glue for the ec2:DescribeSubnets permission.

Error: Failed to Call ec2:DescribeSecurityGroups

  • Check the policy passed to AWS Glue for the ec2:DescribeSecurityGroups permission.

Error: Could Not Find Subnet for AZ

  • The Availability Zone might not be available to AWS Glue. Create and use a new subnet in a different Availability Zone from the one specified in the message.

Error: Job Run Exception for Connection List with Multiple Subnet or AZ

When running a job, validation fails with the exception: CONNECTION_LIST_CONNECTION_WITH_MULTIPLE_SUBNET_ID and CONNECTION_LIST_CONNECTION_WITH_MULTIPLE_AZ.

  • If your job has multiple connections, they can't be in different Availability Zones or subnets. Ensure that all connections in a job are in the same Availability Zone, or edit the job to remove connections so that only connections that are in the same Availability Zone are required.

Error: Job Run Exception When Writing to a JDBC Target

When you are running a job that writes to a JDBC target, the job might encounter errors in the following scenarios:

  • If your job writes to a Microsoft SQL Server table, and the table has columns defined as type Boolean, then the table must be predefined in the SQL Server database. When you define the job on the AWS Glue console using a SQL Server target with the option Create tables in your data target, don't map any source columns to a target column with data type Boolean. You might encounter an error when the job runs.

    You can avoid the error by doing the following:

    • Choose an existing table with the Boolean column.

    • Edit the ApplyMapping transform and map the Boolean column in the source to a number or string in the target.

    • Edit the ApplyMapping transform to remove the Boolean column from the source.

  • If your job writes to an Oracle table, you might need to adjust the length of names of Oracle objects. In some versions of Oracle, the maximum identifier length is limited to 30 bytes or 128 bytes. This limit affects the table names and column names of Oracle target data stores.

    You can avoid the error by doing the following:

    • Name Oracle target tables within the limit for your version.

    • The default column names are generated from the field names in the data. To handle the case when the column names are longer than the limit, use ApplyMapping or RenameField transforms to change the name of the column to be within the limit.

Error: Amazon S3 Timeout

If AWS Glue returns a connect timed out error, it might be because it is trying to access an Amazon S3 bucket in another AWS Region.

  • An Amazon S3 VPC endpoint can only route traffic to buckets within an AWS Region. If you need to connect to buckets in other Regions, a possible workaround is to use a NAT gateway. For more information, see NAT Gateways.

Error: Amazon S3 Access Denied

If AWS Glue returns an access denied error to an Amazon S3 bucket or object, it might be because the IAM role provided does not have a policy with permission to your data store.

  • An ETL job must have access to an Amazon S3 data store used as a source or target. A crawler must have access to an Amazon S3 data store that it crawls. For more information, see Step 2: Create an IAM Role for AWS Glue.

Error: Amazon S3 Access Key ID Does Not Exist

If AWS Glue returns an access key ID does not exist error when running a job, it might be because of one of the following reasons:

  • An ETL job uses an IAM role to access data stores, confirm that the IAM role for your job was not deleted before the job started.

  • An IAM role contains permissions to access your data stores, confirm that any attached Amazon S3 policy containing s3:ListBucket is correct.

Error: Job run fails when accessing Amazon S3 with an s3a:// URI

If a job run returns an an error like Failed to parse XML document with handler class , it might be because of a failure trying to list hundreds of files using the using an s3a:// URI. Access your data store using an s3:// URI instead. The following exception trace highlights the errors to look for:

Error: No Private DNS for Network Interface Found

If a job fails or a development endpoint fails to provision, it might be because of a problem in the network setup.

  • If you are using the Amazon provided DNS, the value of enableDnsHostnames must be set to true. For more information, see DNS.

Error: Development Endpoint Provisioning Failed

If AWS Glue fails to successfully provision a development endpoint, it might be because of a problem in the network setup.

  • When you define a development endpoint, the VPC, subnet, and security groups are validated to confirm that they meet certain requirements.

  • If you provided the optional SSH public key, check that it is a valid SSH public key.

  • Check in the VPC console that your VPC uses a valid DHCP option set. For more information, see DHCP option sets.

  • If after a few minutes, the development endpoint Provisioning status changes to FAILED and the failure reason is DNS related, for example, Reverse dns resolution of ip 10.5.237.213 failed, check your DNS setup. For more information, see Setting Up DNS in Your VPC.

  • If the cluster remains in the PROVISIONING state, contact AWS Support.

Error: Notebook Server CREATE_FAILED

If AWS Glue fails to create the notebook server for a development endpoint, it might be because of one of the following problems:

  • AWS Glue passes an IAM role to Amazon EC2 when it is setting up the notebook server. The IAM role must have a trust relationship to Amazon EC2.

  • The IAM role must have an instance profile of the same name. When you create the role for Amazon EC2 with the IAM console, the instance profile with the same name is automatically created. Check for an error in the log regarding an invalid instance profile name iamInstanceProfile.name. For more information, see Using Instance Profiles.

  • Check that your role has permission to access aws-glue* buckets in the policy that you pass to create the notebook server.

Error: Local Notebook Fails to Start

If your local notebook fails to start and reports errors that a directory or folder cannot be found, it might be because of one of the following problems:

  • If you are running on Microsoft Windows, make sure that the JAVA_HOME environment variable points to the correct Java directory. It's possible to update Java without updating this variable, and if it points to a folder that no longer exists, Zeppelin notebooks fail to start.

Error: Notebook Usage Errors

When using an Apache Zeppelin notebook, you might encounter errors due to your setup or environment.

  • You provide an IAM role with an attached policy when you created the notebook server. If the policy does not include all the required permissions, you might get an error such as assumed-role/name-of-role/i-0bf0fa9d038087062 is not authorized to perform some-action AccessDeniedException. Check the policy that is passed to your notebook server in the IAM console.

  • If the Zeppelin notebook does not render correctly in your web browser, check the Zeppelin requirements for browser support. For example, there might be specific versions and setup required for the Safari browser. You might need to update your browser or use a different browser.

Error: Running Crawler Failed

If AWS Glue fails to successfully run a crawler to catalog your data, it might be because of one of the following reasons. First check if an error is listed in the AWS Glue console crawlers list. Check if there is an exclamation icon next to the crawler name and hover over the icon to see any associated messages.

  • Check the logs for the crawler run in CloudWatch Logs under /aws-glue/crawlers.

Error: Upgrading Athena Data Catalog

If you encounter errors while upgrading your Athena Data Catalog to the AWS Glue Data Catalog, see the Amazon Athena User Guide topic Upgrading to the AWS Glue Data Catalog Step-by-Step.
