Sangjin Lee created YARN-2600:
Summary: if the container is killed during localization
outstanding public cache localization tasks should be cancelled
Project: Hadoop YARN
Issue Type: Improvement
Affects Versions: 2.4.0
Reporter: Sangjin Lee
We came across a situation (partly related with HDFS-7005) where a large number
of public cache localization tasks were queued in the public localizer thread
pool but the container is killed during localization (as it went over the
What's not helpful in this situation is that any work item that's queued will
still be serviced by the resource localization service which is wasteful. And
that may further delay localization efforts of other containers.
It would be good if we can cancel the pending localization tasks when the
container is killed.
