BELUGA BEHR created YARN-7368:
---------------------------------
Summary: 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
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.
