Subject Re: is upgradesstables required for 1.1.4 to 1.2.2? (I don't think it is)
Date Wed, 27 Feb 2013 19:40:02 GMT
Hmmmm, wouldn't I have to run upgradesstables BEFORE I start the 1.2.2
node?  But running upgradesstables as I recall required cassandra to be
running.....so does it somehow understand the old format when it starts I
suspect?

I am thinking I just keep the node out of the ring while I run the
upgradesstables, correct? But of course am not sure how to start a 1.2.2
node such that it does not join the cluster.

Thanks,
Dean
