[jira] Created: (PIG-1596) NPE's thrown when attempting to load hbase columns containing null values

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.

Jeff Zhang commented on PIG-1596:
---------------------------------

George, thanks for your suggestion. And I believe you are using latest HBaseStorage in trunk. What you pointed at is really a problem, and I have another solution for this. If the cell is null,  we put an empty byte array in DataByteArray, I think it should been the LoadFunc's reponponslibity to handle null cell.

---------------------------------

Combine the new test case with existing ones. And commit the patch to both trunk and branch-0.8

----------------------------------------

Works just as well with less files modified. Thanks Jeff. How about the bin/pig modification? Is it ok or am I missing a step in my build process? Without it, when I download trunk and build, I get NoClassDefFoundError errors out of the box when I attempt to rum in grunt mode.

+1

before committing, do you mind combining the new test with one of the existing ones? Trying to keep the test suite at under 24 hours :)

----------------------------------------

Jeff,
I think it's clearer if you insert null into the tuple, not an empty DataByteArray (and assertNull in the test)

George, the SNAPSHOT thing is a real bug, thanks for catching that, this happened when pig was made available through maven in PIG-1334.

I'll create a separate ticket for that.
