Chris Riccomini updated YARN-864:
---------------------------------
Description:
Hey Guys,
I'm running YARN 2.0.5-alpha with CGroups and stateful RM turned on, and I'm
seeing containers getting leaked by the NMs. I'm not quite sure what's going on
-- has anyone seen this before? I'm concerned that maybe it's a
mis-understanding on my part about how YARN's lifecycle works.
When I look in my AM logs for my app (not an MR app master), I see:
2013-06-19 05:34:22 AppMasterTaskManager [INFO] Got an exit code of -100. This
means that container container_1371141151815_0008_03_000002 was killed by YARN,
either due to being released by the application master or being 'lost' due to
node failures etc.
2013-06-19 05:34:22 AppMasterTaskManager [INFO] Released container
container_1371141151815_0008_03_000002 was assigned task ID 0. Requesting a new
container for the task.
The AM has been running steadily the whole time. Here's what the NM logs say:

The same holds true for container_1371141151815_0006_01_001598. When I look in
the container logs, it's just happily running. No kill signal appears to be
sent, and no error appears.
Lastly, the RM logs show no major events around the time of the leak (5:35am).
I am able to reproduce this simply by waiting about 12 hours, or so, and it
seems to have started happening after I switched over to CGroups and LCE, and
turned on stateful RM (using file system).
Any ideas what's going on?
Thanks!
