-------------------------------
Summary: RMContainerImpl does not handle event EXPIRE at state
RUNNING
Key: YARN-214
URL: https://issues.apache.org/jira/browse/YARN-214
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.0.1-alpha, 0.23.3
Reporter: Jason Lowe
RMContainerImpl has a race condition where a container can enter the RUNNING
state just as the container expires. This results in an invalid event
transition error:

EXPIRE needs to be handled (well at least ignored) in the RUNNING state to
account for this race condition.
