Thawan Kooburat updated ZOOKEEPER-1551:
---------------------------------------
Attachment: ZOOKEEPER-1551.patch
- Fixed indentation
- Fixed incorrect comments
- Rebase with trunk
I only print warning message since I use the same code block that we use to
print warning message when we get out-of-order txn. Also, it will print false
positive message when receiving the first message. Since this code block is
going to be rewritten anyway in ZOOKEEPER-1549, so I don't want to put more
effort on it.
I think this patch will go to 3.4.6 only but generate patch based on trunk so
that I can trigger unit test
> Observer ignore txns that comes after snapshot and UPTODATE

> 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.
