I will commit it shortly. > Recover localized resource cache state upon nodemanager restart > --------------------------------------------------------------- > > Key: YARN-1338 > URL: https://issues.apache.org/jira/browse/YARN-1338 > Project: Hadoop YARN > Issue Type: Sub-task > Components: nodemanager > Affects Versions: 2.3.0 > Reporter: Jason Lowe > Assignee: Jason Lowe > Attachments: YARN-1338.patch, YARN-1338v2.patch, > YARN-1338v3-and-YARN-1987.patch, YARN-1338v4.patch, YARN-1338v5.patch, > YARN-1338v6.patch > > > Today when node manager restarts we clean up all the distributed cache files > from disk. This is definitely not ideal from 2 aspects. > * For work preserving restart we definitely want them as running containers > are using them > * For even non work preserving restart this will be useful in the sense that > we don't have to download them again if needed by future tasks. -- This message was sent by Atlassian JIRA (v6.2#6252)
