how to let hmaster read zookeeper's /hbase/unassigned
Hi all,
I removed regions in transition zookeeper path /hbase/unassigned. But I don't want to bring down
master node (the whole cluster will be down). Is there a way to force the master node to load data
from zookeeper? Thanks.

Yes, that will work.

My cluster has a standby master process. If I restart it, will it reload data from zookeeper? If it does, I can shut down the current master and let standby master become the active one. Will that work?

Sorry, I meant "whole cluster" of course.

Just curious why would the whole master be down as a consequence of master
restart?
Thanks,

There is no way to force the master to reload such data from zookeeper
currently.
Thanks,
