Benjamin Reed updated PIG-151:
------------------------------

    Attachment: bz.patch

This patch adds a unit test specifically for reading zero length bzip files and well as another end-to-end test.

The patch also fixes an error related to figuring out the name of the output directory when determining whether this is a bzip file. Note, the source of this error was Hadoop-16, so the fix is specific to Hadoop-16. This will not work with Hadoop-15.

> If a zero length BZIp file is created as a result of a store, the resulting BZIp file will be invalid: it will have part of the BZip header, but it will be missing everything else. The BZip library does not behave correctly when a BZip file is created and nothing is written before the close.
