don't get deleted
-----------------------------------------------------------------------------------------------
Key: PIG-1391
URL: https://issues.apache.org/jira/browse/PIG-1391
Project: Pig
Issue Type: Bug
Affects Versions: 0.7.0
Reporter: Thejas M Nair
Fix For: 0.7.0
Pig unit test runs leave behind files in temp dir (/tmp) and there are too many
files in the directory over time.
Most of the files are left behind by MiniCluster . It closes/shutsdown
MiniDFSCluster, MiniMRCluster and the FileSystem that it has created when the
constructor is called, only in finalize(). And java does not guarantee that
finalize() will be called.
