Appreciate it! > 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 > Fix For: 2.9.0, 3.0.0 > > Attachments: YARN-7244-branch-2.8.001.patch, > YARN-7244-branch-2.8.002.patch, YARN-7244.001.patch, YARN-7244.002.patch, > YARN-7244.003.patch, YARN-7244.004.patch, YARN-7244.005.patch, > YARN-7244.006.patch, YARN-7244.007.patch, YARN-7244.008.patch, > YARN-7244.009.patch, YARN-7244.010.patch, YARN-7244.011.patch, > YARN-7244.012.patch, YARN-7244.013.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
