--------------------------------------------
Here is the list of dependencies and status of the blocker patch which I am
involved with
3.4.6 blocker issues:
ZOOKEEPER-1549 -> partially fixed by ZOOKEEPER-1558
ZOOKEEPER-1551 -> fixed but depends on ZOOKEEPER-1552. If we don't want to
include ZOOKEEPER-1552,the patch need more work
3.5 blocker issues:
ZOOKEEPER-1549 -> need rework and also depends on ZOOKEEPER-1413,ZOOKEEPER-1642
ZOOKEEPER-1551 -> fixed by ZOOKEEPER-1549 and depends on ZOOKEEPER-1552
We might need to discuss in dev list to get all the block issue resolved

> In Learner.java, txns which comes after the learner has taken the snapshot
> (after NEWLEADER packet) are stored in packetsNotCommitted. The follower has
> special logic to apply these txns at the end of syncWithLeader() method.
> However, the observer will ignore these txns completely, causing data
> inconsistency.
