Description

In https://builds.apache.org/job/Pig-spark/191/, it shows that
two regression unit test failures are added:
1.TestSecondarySortSpark#testSecondarySortSpark#testNestedDistinctEndToEnd1
2.TestSecondarySortSpark#testSecondarySortSpark#org.apache.pig.spark.TestSecondarySortSpark.testNestedDistinctEndToEnd2

the reason why these two unit test fail is the result of group is not sorted in spark mode.
