--------------------------------------
Summary: Handle FSPreemptionThread crashing due to a
RuntimeException
Key: YARN-5798
URL: https://issues.apache.org/jira/browse/YARN-5798
Project: Hadoop YARN
Issue Type: Sub-task
Components: fairscheduler
Affects Versions: 2.9.0
Reporter: Karthik Kambatla
YARN-5605 added an FSPreemptionThread. The run() method catches
InterruptedException. If this were to run into a RuntimeException, the
preemption thread would crash. We should probably fail the RM itself (or
transition to standby) when this happens.
