Yeah. In that case you need to wipe the corresponding znode under /hbase/table. We need a way to do so automatically.

Thanks. So I guess even is you wipe only a single table you will have the same issue, right? Not just only if you wipe the entire /hbase folder? 2013/12/13 lars hofhansl <[email protected]> This is (somewhat expected) after HBASE-7600. A wipe of HDFS needs to be followed by a wipe of the /hbase folder in ZK. >I filed HBASE-10145 for further discussion, yesterday. > >-- Lars > > > >________________________________ > From: Jean-Marc Spaggiari <[email protected]> >To: dev <[email protected]> >Sent: Friday, December 13, 2013 2:27 PM >Subject: Re: ANN: The third hbase-0.96.1 release candidate is available for >download > > > >Facing something strange... > >I have been able to download and check the signature.
