[jira] [Commented] (CASSANDRA-13061) C* driver hangs forever in
case of concurrent CREATE TABLE IF NOT EXISTS

Aleksey Yeschenko commented on CASSANDRA-13061:
-----------------------------------------------
It's not related to CASSANDRA-5025, but it is known behaviour.
CASSANDRA-9425 will take care of it soon, for single-node clusters.
