Hi Nickolai,

Thanks for the logs!

Certainly this seems to put your cluster almost immediately into a bad state:

Did you recently upgrade? It looks like you are using 0.2.0 from trunk. Do all hbase-0.2.0.jar
files have the same md5sum? Are there any stray hbase-0.2.0-dev.jar files in your classpath?
