Re: Node manager crashing when running an app requiring 100 containers on hadoop-2.1.0-beta RC0
How many containers are you running per node?

Re: Node manager crashing when running an app requiring 100 containers on hadoop-2.1.0-beta RC0
Hi Arun, I was running on a single node cluster, so all my 100+ containers are on single node. And, the problem is gone when I increased YARN_HEAP_SIZE to 2GB.

Hi Kishore, It seems that system doesn't have enough resources to launch a new thread. Could you check the system is affordable to launch the configured containers and try increasing the native memory available in the system by reducing the no of running processes in the system.

Re: Node manager crashing when running an app requiring 100 containers on hadoop-2.1.0-beta RC0
Hi Devaraj, I used to run this application with the same number of containers successfully on previous version, i.e. hadoop-2.0.4-alpha. Is it failing with the new version, because YARN itself is also adding some more threads than the previous versions?
