------------------------------
Summary: Add retry-times to let NM re-launch container when it
fails to run
Key: YARN-3998
URL: https://issues.apache.org/jira/browse/YARN-3998
Project: Hadoop YARN
Issue Type: New Feature
Reporter: Jun Gong
Assignee: Jun Gong
I'd like to add a field(retry-times) in ContainerLaunchContext. When AM
launches containers, it could specify the value. Then NM will re-launch the
container 'retry-times' times when it fails to run(e.g.exit code is not 0).
It will save a lot of time. It avoids container localization. RM does not need
to re-schedule the container. And local files in container's working directory
will be left for re-use.(If container have downloaded some big files, it does
not need to re-download them when running again.)
We find it is useful in systems like Storm.
