---------------------------------
Summary: Add more required API's to MergeManager interface
Key: MAPREDUCE-6332
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6332
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Rohith
Assignee: Rohith
MR provides ability to the user for plugin custom ShuffleConsumerPlugin using
*mapreduce.job.reduce.shuffle.consumer.plugin.class*. When the user is allowed
to use this configuration as plugin, user also interest in implementing his own
MergeManagerImpl.
But now , user is forced to use MR provided MergeManagerImpl instead of custom
MergeManagerImpl when user is using shuffle.consumer.plugin class. There should
be well defined API's in MergeManager that can be used for any implementation
without much effort to user for custom implementation.
