--------------------------------------
Summary: Move app starvation identification out of the update
thread
Key: YARN-6246
URL: https://issues.apache.org/jira/browse/YARN-6246
Project: Hadoop YARN
Issue Type: Sub-task
Components: fairscheduler
Affects Versions: 2.9.0
Reporter: Karthik Kambatla
Assignee: Karthik Kambatla
Given the update thread holds the scheduler write-lock, we are probably better
of computing starvation and identification of starved apps in a different
thread.
I am averse to adding a thread that runs on a *configurable timeout*, but maybe
we could trigger this thread after every update run, or do this in the update
thread but outside of the write-lock.
