Jose Luis López created HADOOP-19963:
----------------------------------------
Summary: Shut down leaked mini-cluster instances in hadoop-distcp
and hadoop-streaming
Key: HADOOP-19963
URL: https://issues.apache.org/jira/browse/HADOOP-19963
Project: Hadoop Common
Issue Type: Test
Reporter: Jose Luis López
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.
