Subject upgrade 1.1.4 to 1.2.2 around 120x performance loss(one node only)
Date Fri, 01 Mar 2013 18:18:06 GMT
I setup a QA system copying our production system which was accidentally SimpleSnitch I found
out but we are only in one datacenter right now luckily.

I have 4 nodes on 1.1.4 and I ran the following commands to upgrade ONE SINGLE NODE to 1.2.2

#on the node itself
nodetool drain
nodetool -h localhost -p 7199 snapshot databus5 -t 1.2.2a
rm /opt/cassandra
ln -s /opt/cassandra-1.2.2 /opt/cassandra
#BACK to cassandra(it won't run as root anyways as not in path)
cassandra -Dcassandra.join_ring=false -Dcassandra.start_rpc=false
nodetool upgradesstables databus5
Kill {pid} #take cassandra back down
Cassandra #start cassandra

My web page now takes 2 minutes/120 seconds to return back to me.  Is anyone else experiencing
