-------------------------------
Summary: When RM is catching up with node updates then it should
not expire acquired containers
Key: YARN-433
URL: https://issues.apache.org/jira/browse/YARN-433
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Bikas Saha
Assignee: Xuan Gong
RM expires containers that are not launched within some time of being
allocated. The default is 10mins. When an RM is not keeping up with node
updates then it may not be aware of new launched containers. If the expire
thread fires for such containers then the RM can expire them even though they
may have launched.
