• Affects Version/s: 0.23.0
• Fix Version/s: 0.23.1
• Component/s: applicationmaster, mrv2
• Hadoop Flags: Reviewed
• Release Note: Fixed bugs in ContainerLauncher of MR AppMaster due to which per-container connections to NodeManager were lingering long enough to hit the ulimits on number of processes.

Description

Karams just found this. The usual sort job on a 350 node cluster hung due to OutOfMemory and eventually failed after an hour instead of the usual odd 20 minutes.
