Subject [jira] Commented: (PIG-1596) NPE's thrown when attempting to load hbase columns containing null values
Date Mon, 06 Sep 2010 02:07:33 GMT

    [ https://issues.apache.org/jira/browse/PIG-1596?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12906418#action_12906418

Jeff Zhang commented on PIG-1596:

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

>    Affects Versions: 0.7.0

> 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.
