Subject Unbalanced ring after upgrade!
Date Thu, 14 Feb 2013 13:32:05 GMT
Hello,

We just upgraded from 1.1.2->1.1.9.  We utilize the byte ordered 
partitioner (we generate our own hashes).  We have not yet upgraded 
sstables.

Before the upgrade, we had a balanced ring.

After the upgrade, we see:

10.0.4.22       us-east     1a          Up     Normal  77.66 GB

Restarting a node essentially changes who own 99% of the ring.

Given we use an RF of 3, and LOCAL_QUORUM consistency for everything, 
and we are not seeing errors, something seems to be working correctly.  
Any idea what is going on above?  Should I be alarmed?
