Kuhu Shukla updated TEZ-3804:
-----------------------------
Attachment: TEZ-3804.001.patch
First cut of the patch. Includes some test changes to existing test as they
expected "copySucceeded" to be called irrespective of the index record size.
Added a test that checks is copySucceeded is called for empty partitions or not.
> FetcherOrderedGrouped#setupLocalDiskFetch should ignore empty partition
> records

> Similar to the copyMapOutput() logic, local fetches can also ignore
> indexRecords that are empty (hasData == false) to avoid duplicate fetch
> warnings.
