-----------------------------------

             Summary: Add MirrorJournal ( server side implementation) to handle the journals
from Primary cluster
                 Key: HDFS-6514
                 URL: https://issues.apache.org/jira/browse/HDFS-6514
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode
            Reporter: Vinayakumar B


This targets the serverside implementation of handling journals sent by the primary cluster
via MirrorJournalManager.

This service will be launched in mirror cluster's active namenode. It receives the journal
RPC requests from MirrorJournalManager and processes edits and writes it to local shared storage
and applies on the in-memory namespace.
