liyunzhang_intel created PIG-4596:
-------------------------------------

             Summary: Fix unit test failures about MergeJoinConverter in spark mode
                 Key: PIG-4596
                 URL: https://issues.apache.org/jira/browse/PIG-4596
             Project: Pig
          Issue Type: Sub-task
            Reporter: liyunzhang_intel
            Assignee: liyunzhang_intel


using following command to test TestMergeJoin
ant -Dtestcase=TestMergeJoin -Dexectype=spark  -Dhadoopversion=23  test
 
Following unit test fails:
org.apache.pig.test.TestMergeJoin.testMergeJoinWithNulls

The reason why these unit test fail is because null value from table a and table b are considered same when table a merge join table b.
