> 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.
