Flavio Junqueira commented on ZOOKEEPER-1551:
---------------------------------------------
I'm really confuse about all the sequence of jiras that we need to get it.
According to my bookkeeping, we have: ZOOKEEPER-1413, ZOOKEEPER-1549,
ZOOKEEPER-1552, ZOOKEEPER-1642, ZOOKEEPER-1667, ZOOKEEPER-1674. Am I missing
any? Now, I'd like to understand which order we need to follow to get them in.
Should we have a discussion on the dev list about it?

> 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.
