Subject Re: [resend] region server of -ROOT- table is dead, but not reassigned
Date Wed, 20 Feb 2013 06:12:55 GMT
Ideally the ROOT table should be reassigned once the RS carrying ROOT goes
down.  This should happen automatically.

May be what does your logs say.  That would give us an insight.

Before that if you can restart your master it may solve this problem.  Even
then if it persists try to delete the zk data and restart the cluster.
