Subject Re: Could not reach schema agreement when adding a new node.
Date Sun, 25 Sep 2011 09:10:33 GMT
Check the schema agreement using the CLI by running describe cluster;  it will tell you if
they are in agreement.

it may have been a temporary thing while the new machine was applying it's schema. 

if the nodes are not in agreement or you want to dig deeper look for log messages from "Migration".


Cheers
