Subject Re: Exception starting HBase 0.20.1
Date Thu, 15 Oct 2009 20:11:43 GMT
Same version (0.20.1) everywhere.

The exception happens when the HBase cluster is starting, so I think the
master is the one making requests. The master log is clear.

I thought the problem could be related to the fact that I'm enabling the
indexing option (properties hbase.regionserver.class and
hbase.regionserver.impl in hbase-site.xml) but I disabled it and the error
persists. See log bellow.

I think I'm making a dumb mistake, but I double checked everything and can't
see anything wrong with my cluster setup. Could someone please confirm if
something that should be in 0.20.1 was removed by accident?
