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.
> 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.
