Hey there,

I'm trying to start up a new HBase instance running against Hadoop
.20. Hadoop has been running for a week, and I just built the latest
checkout from trunk. This is the error I'm getting. Any ideas?

    One other thought, one thing you should ensure is both the master and the

    Hey there,

    I'm trying to start up a new HBase instance running against Hadoop
