Jose Luis López updated MAPREDUCE-7542:
---------------------------------------
Priority: Minor (was: Major)
> Shut down leaked mini-cluster instances
> ---------------------------------------
>
> Key: MAPREDUCE-7542
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7542
> Project: Hadoop Map/Reduce
> Issue Type: Test
> Components: test
> Reporter: Jose Luis López
> Priority: Minor
> Original Estimate: 8h
> Remaining Estimate: 8h
>
> Part of the mini-cluster leak scan recorded in HDFS-17957, I came across with
> two leaks in the MAPREDUCE project:
>
> * TestNNBench#testNNBenchCrossCluster shuts its dfsCluster down only on the
> happy path, so the cluster leaks exactly when the test fails.
> * TestDelegationToken holds a cluster in a field with no teardown in the class
> or its ancestors.
>
> Impact: a leaked cluster keeps threads, heap and ports alive under the
> remaining tests of the class, and a failure on the happy-path-only pattern can
> cascade into bogus failures of later tests in the same class.
>
> The fixes are mechanical - shutdown in a finally block, and a teardown method.
>
> Test-scope only; no production code is touched.
