Troubleshoot a failed cluster

This section walks you through the process of troubleshooting a cluster that has failed. This means that the cluster terminated with an error code.


When an EMR cluster terminates with an error, the DescribeCluster and ListClusters APIs return an error code and an error message. For some cluster errors, the ErrorDetail data array can also help you troubleshoot the failure. For more information, see Error codes with ErrorDetail information.

If your cluster runs but takes a long time to return results, see Troubleshoot a slow cluster.
