[jira] [Created] (MAPREDUCE-4990) Construct debug strings conditionally in ShuffleHandler.Shuffle#sendMapOutput()

Karthik Kambatla created MAPREDUCE-4990:
-------------------------------------------

             Summary: Construct debug strings conditionally in ShuffleHandler.Shuffle#sendMapOutput()
                 Key: MAPREDUCE-4990
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4990
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.23.5, 2.0.3-alpha
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla
            Priority: Trivial


In {{#sendMapOutput()}}, the debug statements are not wrapped in the customary {{#isDebugEnabled()}} condition. Given this piece of code is critical for performance, it would be nice to fix it.
