BELUGA BEHR updated YARN-7368:
------------------------------
Affects Version/s: 3.0.0
> Yarn Work-Preserving Better Handling Failed Disk
> ------------------------------------------------
>
> Key: YARN-7368
> URL: https://issues.apache.org/jira/browse/YARN-7368
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager, yarn
> Affects Versions: 2.8.1, 3.0.0
> Reporter: BELUGA BEHR
>
> If the drive that hosts the {{yarn.nodemanager.recovery.dir}} is broken then
> the entire NodeManager will not start. Please improve this so that if the
> directory is not able to be created/accessed then the recovery portion of the
> NM is simply skipped and the NM continues to operate as normal.
> It may also be beneficial to be able to define multiple directories, like
> YARN logging directories, so that if one drive fails, not all of the recovery
> data is lost.
