             Summary: Delegate bzip processing to Hadoop
                 Key: PIG-4600
                 URL: https://issues.apache.org/jira/browse/PIG-4600
             Project: Pig
          Issue Type: Improvement
            Reporter: Daniel Dai
            Assignee: Daniel Dai
             Fix For: 0.16.0


Pig handling bzip within its own codebase. I am not very sure but that's 
probably due to history reason. Hadoop does not support splittable bzip until 
0.21 (HADOOP-4012). If so, we shall remove the bzip2 module in Pig and delegate 
to Hadoop.

In particular, Pig does not support bzip2 concatenation. Once we delegate bzip 
to Hadoop, this issue will be solved.
