Re: [VOTE] Merge HDFS-3077 (QuorumJournalManager) branch to trunk
Suresh and I are still reviewing this design and patch.
The 3077 code along with  the code pulled from 3092 is fairly substrantial. The design is also fairly complex and involved.
I  would request that we postpone the merge for another week to give folks time to review this fully.
