Tyler Hobbs commented on CASSANDRA-9453:
----------------------------------------
Also, I apologize for the slow response on this one, but I'm thinking this fix
might need to be in for 2.2.0-rc1. [~krummas] do we need CASSANDRA-9317 in 2.2
for anything? The only ticket mentioned on that is scheduled for 3.x, so it
seems like we could safely revert it just for 2.2 until we figure out a proper
fix.

> This error was on the trunk dtests, but I assume 2.2 is affected at a

> the same potential problem.
