Subject Re: Force remove table
Date Tue, 14 Oct 2014 08:27:56 GMT
Kristoffer,

It looks like this is described in
https://issues.apache.org/jira/browse/HBASE-8912. In short, stop HBase,
remove the affected znode, restart HBase, and then run hbase hbck
-fixAssignments . Longer term, it may be worth upgrading past 0.94.16, if
possible, because this issue has since been resolved.

Let us know how it goes!
