Rakesh R commented on BOOKKEEPER-294:
-------------------------------------
>From the discussions we have the following solutions:-
# delete the znode in shutdownhook
# delete the znode in startup
# if znode exists, wait till the session expiry (here changing the zkTimeout
and starts back will cause inconsistencies)
I'd like to know which among is good. Hi folks, please help us to find good
approach:-)
