Subject Re: Cassandra 1.1.2 -> 1.1.8 upgrade
Date Mon, 11 Feb 2013 08:54:53 GMT
Not sure this will be useful for you but "nodetool drain" doesn't work
properly well for a while. If you are using counters I recommend you to
remove commit logs after you drained ans stopped the node, before
restarting the node to avoid replaying counts.

Hope this will help,

Alain
