This has resulted in this waiter not returning successfully when an EMR cluster goes into a WAITING state, breaking functionality in aws emr tool (see aws/aws-cli#1007). In Amazon EMR versions 5. This will take about 10 minutes after the cluster is in a Waiting state. The state change event carries the information about the new state of the cluster, so there is no need to call describe_cluster, therefore the lambda does not count towards EMR endpoint quota. 1. If the tag is not present, the cluster remains The easiest method would be used to Amazon EMR Metrics and Dimensions for Amazon CloudWatch. , bootstrap actions and cluster steps, then cloning will be the exact same. RunJobFlow creates and starts running a new cluster (job flow). You can terminate a cluster that fails to leave the STARTING state or is unable I am trying to use Lambda function to check the status of waiting/running EMR so that I can terminate them using lambda function.

WAITING: INFO: EMR cluster state change. There is a parameter named KeepJobFlowAliveWhenNoSteps to stop terminating EMR job flow when all steps completed, you can use it. Set this value to true so that IAM principals in the Amazon Web Services account associated with the cluster can perform Amazon EMR actions on the cluster that their IAM policies allow. The resources created by the emr-on-eks addon include: While starting the notebook which is on AWS EMR cluster using boto3 it's not entering into 'running' state so I'm not sure whether my script is working properly or not. running := "RUNNING" waiting := ". If an instance group is in the SUSPENDED state, and the cluster is in a WAITING state, you can add a cluster step to reset the desired number of core and task nodes. By breaking down the usage of individual applications running in your EMR cluster, Amazon EMR cluster ClusterId (ClusterName) is being created in zone (AvailabilityZoneID), which was chosen from the specified Availability Zone options. Any data not saved elsewhere, such as in an Amazon S3 bucket, is lost. This is an issue for long running clusters that reach the WAIT state after all steps have been completed. Type: Array of ErrorDetail objects. We recommend you use a cluster with at least four core nodes for production workloads. This is very useful for probing various log files before the cluster is terminated. Submitting Work to the Cluster. jars.
