Kuhu Shukla created YARN-7244:
---------------------------------
Summary: ShuffleHandler is not aware of disks that are added
Key: YARN-7244
URL: https://issues.apache.org/jira/browse/YARN-7244
Project: Hadoop YARN
Issue Type: Bug
Reporter: Kuhu Shukla
Assignee: Kuhu Shukla
The ShuffleHandler permanently remembers the list of "good" disks on NM startup. If disks
later are added to the node then map tasks will start using them but the ShuffleHandler will
not be aware of them. The end result is that the data cannot be shuffled from the node leading
to fetch failures and re-runs of the map tasks.
