SequenceFile.Sorter.MergeQueue.next does an unnecessary copy of the key
-----------------------------------------------------------------------
Key: HADOOP-3365
URL: https://issues.apache.org/jira/browse/HADOOP-3365
Project: Hadoop Core
Issue Type: Bug
Components: io
Affects Versions: 0.17.0
Reporter: Arun C Murthy
Assignee: Arun C Murthy
Fix For: 0.18.0
SequenceFile.Sorter.MergeQueue.next does an unnecessary copy of the *rawKey*.
We should remove that copy, and move code which adjusts the _heap_ from
{{next()}} to {{getKey()}}, which should then just return {{ms.getKey()}},
thereby eliminating the extra copy.
