Can you paste the trace for this container on the NodeManager? Specifically any exception messages.

The problem is the process that is running with that container continue to run while the container's local directory is already cleaned up. I investigated my code to understand the reason this happens and could not figure out. Anyone ever experience this ? If yes please share. Also please give the details about how the containers completion event is triggered and what make it possible for a process to continue running after it is marked as completed.
