Allen Wittenauer updated MAPREDUCE-4647: ---------------------------------------- Fix Version/s: (was: 3.0.0) > We should only unjar jobjar if there is a lib directory in it. > -------------------------------------------------------------- > > Key: MAPREDUCE-4647 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4647 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Affects Versions: 0.23.3 > Reporter: Robert Joseph Evans > Assignee: Robert Joseph Evans > Fix For: 2.0.2-alpha, 0.23.4 > > Attachments: MR-4647-branch-0.23.txt, MR-4647.txt, MR-4647.txt, > MR-4647.txt, MR-4647.txt > > > For backwards compatibility we recently added made is so we would unjar the > job.jar and add anything to the classpath in the lib directory of that jar. > But this also slows job startup down a lot if the jar is large. We should > only unjar it if actually doing so would add something new to the classpath. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
