AddInstanceGroupsAsync(AddInstanceGroupsRequest, CancellationToken) | Initiates the asynchronous execution of the AddInstanceGroups operation. | |
AddJobFlowSteps(AddJobFlowStepsRequest) |
AddJobFlowSteps adds new steps to a running job flow. A maximum of 256 steps are
allowed in each job flow.
If your job flow is long-running (such as a Hive data warehouse) or complex, you may require more than 256 steps to process your data. You can bypass the 256-step limitation in various ways, including using the SSH shell to connect to the master node and submitting queries directly to the software running on the master node, such as Hive and Hadoop. For more information on how to do this, go to Add More than 256 Steps to a Job Flow in the Amazon Elastic MapReduce Developer's Guide. A step specifies the location of a JAR file stored either on the master node of the job flow or in Amazon S3. Each step is performed by the main function of the main class of the JAR file. The main class can be specified either in the manifest of the JAR or by using the MainFunction parameter of the step. Elastic MapReduce executes each step in the order listed. For a step to be considered complete, the main function must exit with a zero exit code and all Hadoop jobs started while the step was running must have completed and run successfully. You can only add steps to a job flow that is in one of the following states: STARTING, BOOTSTRAPPING, RUNNING, or WAITING. |

instead.
DescribeJobFlows returns a list of job flows that match all of the supplied parameters. The parameters can include a list of job flow IDs, job flow states, and restrictions on job flow creation date and time. Regardless of supplied parameters, only job flows created within the last two months are returned. If no parameters are supplied, then job flows matching either of the following criteria are returned:
Amazon Elastic MapReduce can return a maximum of 512 job flow descriptions. |

RemoveTags(RemoveTagsRequest) |
Removes tags from an Amazon EMR resource. Tags make it easier to associate clusters
in various ways, such as grouping clusters to track your Amazon EMR resource allocation
costs. For more information, see Tagging
Amazon EMR Resources.
The following example removes the stack tag with value Prod from a cluster: |
|
RemoveTagsAsync(RemoveTagsRequest, CancellationToken) | Initiates the asynchronous execution of the RemoveTags operation. | |
RunJobFlow(RunJobFlowRequest) |
RunJobFlow creates and starts running a new job flow. The job flow will run the steps
specified. Once the job flow completes, the cluster is stopped and the HDFS partition
is lost. To prevent loss of data, configure the last step of the job flow to store
results in Amazon S3. If the JobFlowInstancesConfigKeepJobFlowAliveWhenNoSteps
parameter is set to TRUE , the job flow will transition to the WAITING
state rather than shutting down once the steps have completed.
For additional protection, you can set the JobFlowInstancesConfig A maximum of 256 steps are allowed in each job flow. If your job flow is long-running (such as a Hive data warehouse) or complex, you may require more than 256 steps to process your data. You can bypass the 256-step limitation in various ways, including using the SSH shell to connect to the master node and submitting queries directly to the software running on the master node, such as Hive and Hadoop. For more information on how to do this, go to Add More than 256 Steps to a Job Flow in the Amazon Elastic MapReduce Developer's Guide. For long running job flows, we recommend that you periodically store your results. |

RunJobFlowAsync(RunJobFlowRequest, CancellationToken) | Initiates the asynchronous execution of the RunJobFlow operation. | |
SetTerminationProtection(SetTerminationProtectionRequest) |
SetTerminationProtection locks a job flow so the Amazon EC2 instances in the cluster
cannot be terminated by user intervention, an API call, or in the event of a job-flow
error. The cluster still terminates upon successful completion of the job flow. Calling
SetTerminationProtection on a job flow is analogous to calling the Amazon EC2 DisableAPITermination
API on all of the EC2 instances in a cluster.
SetTerminationProtection is used to prevent accidental termination of a job flow and to ensure that in the event of an error, the instances will persist so you can recover any data stored in their ephemeral instance storage.
To terminate a job flow that has been locked by setting SetTerminationProtection
to For more information, go to Protecting a Job Flow from Termination in the Amazon Elastic MapReduce Developer's Guide. |
|
SetTerminationProtectionAsync(SetTerminationProtectionRequest, CancellationToken) | Initiates the asynchronous execution of the SetTerminationProtection operation. | |
SetVisibleToAllUsers(SetVisibleToAllUsersRequest) |
Sets whether all AWS Identity and Access Management (IAM) users under your account
can access the specified job flows. This action works on running job flows. You can
also set the visibility of a job flow when you launch it using the VisibleToAllUsers
parameter of RunJobFlow. The SetVisibleToAllUsers action can be called only
by an IAM user who created the job flow or the AWS account that owns the job flow.
|
|
SetVisibleToAllUsersAsync(SetVisibleToAllUsersRequest, CancellationToken) | Initiates the asynchronous execution of the SetVisibleToAllUsers operation. | |
TerminateJobFlows(TerminateJobFlowsRequest) |
TerminateJobFlows shuts a list of job flows down. When a job flow is shut down, any
step not yet completed is canceled and the EC2 instances on which the job flow is
running are stopped. Any log files not already saved are uploaded to Amazon S3 if
a LogUri was specified when the job flow was created.
The maximum number of JobFlows allowed is 10. The call to TerminateJobFlows is asynchronous. Depending on the configuration of the job flow, it may take up to 5-20 minutes for the job flow to completely terminate and release allocated resources, such as Amazon EC2 instances. |
|
TerminateJobFlowsAsync(TerminateJobFlowsRequest, CancellationToken) | Initiates the asynchronous execution of the TerminateJobFlows operation. |
