> 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.
