Are you creating any children? Changing the process group? If so, you may fool the NM into not tracking your child process. john

But looking at the Resource manager's logs , the container completed as normal with exit code of 0 . This is really weird to me.

You can look at the logs for the container on the web-UI. Also look at ResourceManager logs to trace what is happening with this container. Which application is this? MapReduce? Distributed Shell? Or your own custom application? +Vinod Hortonworks Inc. http://hortonworks.com/ On Mon, Jan 20, 2014 at 6:38 AM, REYANE OUKPEDJO <r.oukpe...@yahoo.com<mailto:r.oukpe...@yahoo.com>> wrote: Hi there, I was using hadoop-2.2.0 to run an application that only lunch 3 containers the application master container and 2 more containers that run the job. one of the 2 containers is returning as completed from the Resource Manager's logs as soon as it is launched. 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.
