Please find attached the EMR cluster configuration and please check if the cluster id has been set properly.

As mentioned in snippets we have configured the pipeline and We are trying to run a transformer pipeline on AWS EMR. The pipeline starts properly. It goes into running state, on EMR cluster it completes the run successfully but at control hub, it fails with error “START_ERROR: Application has completed. Clearing staged files..”.  

Pipeline error log message:
This Transformer generated the following error message: "Http failure response for https://na01.hub.streamsets.com/tunneling/rest/3b28673a-87a4-4dcb-a749-13643daf3bff/rest/v1/pipeline/EMRAWS__55c36ec1-2536-4ad6-95d3-d38ae28dd36b__b601f953-5a66-11ed-b8e4-b31442db6663/driverLogs?runCount=1&endingOffset=-1&jobId=55c36ec1-2536-4ad6-95d3-d38ae28dd36b:b601f953-5a66-11ed-b8e4-b31442db6663&jobRunCount=9&TUNNELING_INSTANCE_ID=tunneling-1: 500 Internal Server Error". Check if you can access the Transformer URL from this browser

@akshayp2 :

Spark cluster must be able to access Transformer to send the status, metrics, and offsets for running pipelines. Please configure transformer.base.http.url or cluster call back url  with the one which is accessible from the cluster.
