Todd Lipcon commented on MAPREDUCE-4647:
----------------------------------------
Is this a regression of MAPREDUCE-967, more or less?
> 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: Improvement
> Components: mrv2
> Affects Versions: 0.23.3
> Reporter: Robert Joseph Evans
> Assignee: Robert Joseph Evans

> 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.
