Thejas M Nair updated PIG-1391:
-------------------------------

    Attachment: PIG-1391.06.patch

Patch for 0.6 branch. It reduces the number of temp files being left behind from around 1767
to 135 .  It changes only contents of test/ dir. 

As the patch does not apply to trunk, I have manually run the unit tests and test-patch .
All unit tests succeeded, pasting result of test-patch - 
     [exec] +1 overall.
     [exec]
     [exec]     +1 @author.  The patch does not contain any @author tags.
     [exec]
     [exec]     +1 tests included.  The patch appears to include 208 new or modified tests.
     [exec]
     [exec]     +1 javadoc.  The javadoc tool did not generate any warning messages.
     [exec]
     [exec]     +1 javac.  The applied patch does not increase the total number of javac compiler
warnings.
     [exec]
     [exec]     +1 findbugs.  The patch does not introduce any new Findbugs warnings.
     [exec]
     [exec]     +1 release audit.  The applied patch does not increase the total number of
release audit warnings.

> 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.
