Re: -ROOT-, .META. will stay OFFLINE after installing in hbase-0.94.0
Hi,

what do you means stay OFFLINE ? Can you use hbase shell and do these
queries:

- scan '-ROOT-'
- scan '.META.', {COLUMNS => 'info:server', LIMIT => 10}

Can you go to hbasemaster:60010/zk.jsp and check is zookeeper running in
non-safemode mode ?
