Subject Re: Hbase master not starting
Date Mon, 04 Jan 2016 14:44:47 GMT
I had once exactly this situation, and was able (but that was some
development database, so wasn't super production big deal) to get over it
with:

- Stop HBase
- Copy your table to your new HBase location
- Start your HBase
- Run HBCK until it says all is good and you are sure you have your data
- Repeat for every table you want to move.

I'm quite sure this is not recommended way for anything, but that was the
only way for me once I hit hbase:namespace issue like yours...

Good luck!
