> Part of the mini-cluster leak scan recorded in HDFS-17957, which covers
> hadoop-hdfs-project only. I discovered the following in the HADOOP common
> project:
>
> * TestCopyMapper holds a cluster in a field with no teardown in the class or
> its ancestors.
> * TestMultipleArchiveFiles holds two, dfs and mr, with no teardown.
>
> Impact: a leaked cluster keeps threads, heap and ports alive under the
> remaining tests of the class.
>
> The fixes are mechanical teardown methods. Test-scope only; no production code
> is touched.
