Hi Chiranjeevi,

 

When shutdown is not working can you check stack trace of all containers which are active
using jstack. If your operator has created threads then needs to be cleanly terminated for
JVM to terminate. Also try shutting down the application again using shutdown-app command.

Hi Sanjay,

 

thanks for your response.

 

These days im getting the same issue more frequently. And the suggested solution to kill the
job is not a good idea.

As in our flow Once the first App shutdown successfully,next app will launch and proceed further.

 

Please suggest how we can dealt If an operator is stuck in “teardown()” it can prevent
successful shutdown of the application and it could show up as RUNNING indefinitely. 

 

Thanks

Shutdown requires that an application’s all containers/operators are “torn down” gracefully
as part of processing the latest window. If an operator is stuck in “teardown()” it can
prevent successful shutdown of the application and it could show up as RUNNING indefinitely.

 

If you don’t want to debug these issues in teardown() you can just kill the application
thru the Yarn REST API

Hi Team,

 

In my use case , i have two dags to completed the processing. And iam using curl command to
shutdown the application.

 

But some times we are facing an issue to shutdown the first dag . From DT console we are able
to see that the application has released all the resources but it  remains in  RUNNING state
for infinite time.

 

Please suggest .
