NPE's thrown when attempting to load hbase columns containing null values
-------------------------------------------------------------------------

                 Key: PIG-1596
                 URL: https://issues.apache.org/jira/browse/PIG-1596
             Project: Pig
          Issue Type: Bug
          Components: data
    Affects Versions: 0.7.0
            Reporter: George P. Stathis
             Fix For: 0.8.0, 0.9.0
         Attachments: null_hbase_records.patch

I'm not a committer, but I'd like to suggest the attached patch to handle loading hbase rows
containing null cell values (since hbase is all about sparsly populated data rows). As it
stands, a DataByteArray can be created with a null mData if a cell has no value, which causes
NPEs by simply attempting to load a row containing the null cell in question.

PS: the attached patch also contains a slight change to the bin/pig executable to point to
the build/pig-*-SNAPSHOT.jar and not the build/pig-*-dev.jar (the latter no longer seems to
exist). If you prefer a separate patch for this, I'll be happy to submit it.
