Subject [jira] [Created] (MAPREDUCE-6756) native map output collector should be able to handle KV larger than io.sort.mb
Date Tue, 16 Aug 2016 03:45:22 GMT
He Tianyi created MAPREDUCE-6756:
------------------------------------

             Summary: native map output collector should be able to handle KV larger than
io.sort.mb
                 Key: MAPREDUCE-6756
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6756
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: nativetask
    Affects Versions: 2.6.0
            Reporter: He Tianyi


Currently exception is thrown if kvLength > io.sort.mb.
In rare cases this can occur, especially for hive queries.

Maybe we could implement a 'spill single record' function.
