Resolution: Fixed
Closing this as stale.
> MiniMRCluster should have an idempotent shutdown
> ------------------------------------------------
>
> Key: MAPREDUCE-2824
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2824
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: test
> Reporter: Steve Loughran
>
> It looks on a quick skim-through that the
> org.apache.hadoop.mapred.MiniMRCluster class has nothing to stop a caller
> calling shutdown() more than once, with possible adverse consequences. This
> will normally only show up if a test fails at precisely the wrong place.
