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.
