Amareshwari Sriramadasu updated HADOOP-2019:
--------------------------------------------

    Attachment: patch-2019.txt

Here is a patch supporting .tar, .tgz and .tar.gz files in DistributedCache. I 
pulled out ant-1.7.0 and used org.apache.tools.tar.TarInputStream and 
org.apache.tools.tar.TarEntry for untarring.  Also updated testcase 
TestMiniMRWithDFSCaching to add .tar, .tgz and .tar.gz to cache archive and run 
job.

> DistributedFileCache should support .tgz files in addition to jars and zip 
> files

> Currently the distributed file cache only works with zip and jar archives, 
> which don't work for larger than 2g. We should support .tgz archives also.
