removing the zookeeper data dir did the trick. The master stopped again

persisted there and read again?)

Where was it?  In a file under .META. table dir?

I appended a "grep -r application1 *" below. Note that "application1" is 
the old host name. Must admit that none of it looks very much HBase 
related... :-(


Will put that into our troubleshooting guide right away.

We should do same (smile).



Is there further implications of deleting the zookeeper data dir? And once
we are at it, is there some general information on what to do if you need
to rename nodes (in particular master nodes)?


Data in zk is transient only.  It'd be safe to remove it as long as you are
doing cluster restart.

That's really good to know!

On renaming nodes, my belief is that this is fixed in 0.92.... if 'unknown'
host, we'll reassign it a known server.

Great.
