ramkrishna.s.vasudevan commented on HBASE-7906:
-----------------------------------------------
So if we want async behaviour then we cannot find if the znode exists or not.
Even if it exists we should take some action on that. May be we should
forcefully set the state to OFFLINE or we may have to abort the server.
But for doing it we may have to read the data of the znode.
So can we introduce a config to say if it is ok to check the data and then
asynchronously create znode in OFFLINE state. Because as Jimmy pointed out in
HBASE-7799 this piece of code is aimed at faster execution and hence the async
nature.
Any other suggestions on this?

> The OfflineCallBack does not bother if the znode already exists or not.
> Infact the catch block AM.asyncSetOfflineInZooKeeper() is a dead code.
