Koji Noguchi updated PIG-5201:
------------------------------
Attachment: pig-5201-v09-with-testUtilchange.patch
bq. We can go one step further and make checkQueryOutputs and
checkQueryOutputsAfterSort consistent but this requires more changes elsewhere.
Attaching {{pig-5201-v09-with-testUtilchange.patch}} which does this but not
sure if this just makes the testing more confusing...
You would now need to consider
* if number if integer, long or String,
* if object is actually String or DataByteArray,
* etc, etc
> Null handling on FLATTEN
