Writes from map serialization include redundant checks for accounting space
---------------------------------------------------------------------------

                 Key: HADOOP-3617
                 URL: https://issues.apache.org/jira/browse/HADOOP-3617
             Project: Hadoop Core
          Issue Type: Improvement
          Components: mapred
    Affects Versions: 0.17.0
            Reporter: Chris Douglas
            Assignee: Chris Douglas
             Fix For: 0.19.0


In BlockingBuffer::write, the collector verifies that there is sufficient space to hold metadata
when it returns to MapOutputBuffer::collect. This check is redundant for serialized records
that make more than one call to write.
