Subject [jira] Commented: (PIG-151) Zero length BZip files are not generated correctly
Date Mon, 28 Apr 2008 19:09:56 GMT

Olga Natkovich commented on PIG-151:
------------------------------------

Ben, thanks for figuring this out.

I have reviewed and tested the patch and will commit it once the SVN is back to normal.

I agree that this is pretty hacky. I spoke with Owen and in Hadoop 0.17 things change again
so we need to make more more changes. Fortunately, Hadoop is providing us a way to find the
original name provided by the user via a static method in FileOutputFormat.

Ben, how do we handle gzip files. Do we need to make any changes there?

> 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.
