Rakesh R commented on BOOKKEEPER-773:
-------------------------------------
*Diff*
a) Added 2.3. Verification steps before performing any update operations.
b) Removed setting the newbookiehost to the oldcookie, here considering the
verification steps will make sure that zookeeper and the filesystem is in sync.
Partial failure cases like,
case-1) after 2.4 step assume cmd has crashed/failed(say zk is down)
Ans: Bookie startup will fail as it sees newbookie in the directories. This
will be a hint to the users
case-2) after 2.5 step assume cmd has crashed/failed(say zk is down)
Ans: Bookie will be able to start with only new configuration. If anyone tries
to use old conf, startup will fail as it sees newbookie in the directories.
Secondly, users can do cleanup by reexecuting the cmd by making zk up.
> Provide admin tool to rename bookie identifier in Cookies
