Ashutosh Chauhan updated PIG-926:
---------------------------------
Attachment: mj_phase2_1.patch
Thanks for the review, Pradeep. My response is inline.
Is there a reason MergeJoinIndexer is a subclass of RandomSampleLoader? It does
not use numSamples or skipInterval and has its own getNext() - is there any
benefit to inheritance?
>> Ya, its better not to have that dependency. Now, MergeJoinIndexer doesn't
>> subclass RandomSampleLoader, instead implements LoadFunc itself.
I see that readObject() method has been removed - is this no longer needed?
>> Ya, its not required anymore.
Also for the case where right pipeline returns POStatus.STATUS_ERR, the code
currently ignores it and continues. ..
>> I was following the usual practice of passing down ERR in the pipeline. But
>> in this case it seems to throw ExecException right there. Updated the patch
>> with it.
Updated the patch with these changes.
FindBugs warning is harmless and can be ignored.
