I pulled HBASE-6310 into 0.94.1.
Once that is fixed I'll release an RC.
If metrics deprecation is not done by then it'll need to go into 0.94.2 (or potentially a
future RC).

To follow up on that, 0.94 is only on a dev cluster at the moment and
we're about to deploy a new refresh. One issue that's really a blocker
for us is:

https://issues.apache.org/jira/browse/HBASE-6310 "-ROOT- corruption
when .META. is using the old encoding scheme"

I can't have my clusters fail to boot after some outage because .META.
isn't reachable. We're still digging.

Another issue that I haven't looked into too much yet is that the new
hbck cannot be used on an old cluster.

Right now what I'm getting is not what I usually get but it's:

ERROR: .META. is found on more than one region.
ERROR: Encountered fatal error. Exiting...
Summary:
2 inconsistencies detected.
Status: INCONSISTENT

Although:

So I guess it's something new we need to debug...
