Subject Error messages after rolling updating cassandra from 0.7.0 to 0.7.2
Date Fri, 25 Mar 2011 11:53:58 GMT
Hi everyone, 

I'm running 10 cassandra nodes in total and updated 5 nodes
from 0.7.0 to 0.7.2 one by one like below.

# sudo /etc/init.d/cassandra stop
# sudo yum update cassandra-0.7.2-4
# sudo /etc/init.d/cassandra start

After updating, those 5 updated nodes keep outputting error messages to
/var/lib/cassandra/log/system.log every exactly 5 minutes.

Do you have any idea about this error message? Thanks for your support.
