--------------------------------------
Resolution: Fixed
> TestRecovery.testSpeculative fails if testCrashed fails
> -------------------------------------------------------
>
> Key: MAPREDUCE-6856
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6856
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Peter Bacsko
> Assignee: Peter Bacsko
>
> The test {{testSpeculative}} in
> {{org.apache.hadoop.mapreduce.v2.app.TestRecovery}} is unstable.
> Based on my findings, the test itself is not problematic. It only fails if
> {{testCrashed}} in the same class fails before it.
> The reason is not completely clear to me, but I whenever I explicitly stop
> the MRAppMaster in {{testCrashed}} in a finally block, then the issue
> disappears. I think the reason is that both tests uses the same folder for
> staging.
> Solution: wrap logic in {{testCrashed}} in a try-finally block and then stop
> the MRAppMaster.
