[jira] [Created] (TEZ-1264) Limit support to OnFileSortedOutput

Rohini Palaniswamy created TEZ-1264:
---------------------------------------

             Summary: Limit support to OnFileSortedOutput
                 Key: TEZ-1264
                 URL: https://issues.apache.org/jira/browse/TEZ-1264
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Rohini Palaniswamy


 When we are limiting on unsorted output, we can stop after reaching the count in the Processor. But if limiting has to be done on sorted output in map phase it is not possible as sorting is done by OnFileSortedOutput. If limiting was supported as part of the output, then we can limit records before writing to each part file after Partitioner is applied.
