Subject Re: Adding/Removing regionservers
Date Thu, 02 Jul 2009 16:35:19 GMT
You do not need to restart the system to add or remove regionservers (or 
hdfs datanodes).

You should update your files, yes.  But to add a new regionserver, set 
up all of the configuration files like the other nodes, and then start 
it up:

$HBASE_HOME/bin/hbase-daemon.sh start regionserver


Without seeing what was happening prior to the Scanner expiration in the 
regionserver logs, it's hard to tell what the problem is.  Can you post 
the full logs somewhere?
