Subject [jira] [Commented] (CASSANDRA-6796) StorageProxy may submit hint to itself (with an assert) for CL.Any
Date Wed, 09 Apr 2014 10:19:18 GMT


Ben Hood commented on CASSANDRA-6796:

I'm getting the following error with a 2.0.6 node - is this potentially related?   

ERROR [Native-Transport-Requests:16633] 2014-04-09 10:11:45,811 (line 222)

> StorageProxy.mutate may  produce WriteTimoutException and with ConsistencyLevel.ANY it
tries to submitHint. But submitHint function have assertation - we may not send hints to ourself.
That may lead to exception (in case we're among natural endpoints) and hint will be not submitted
to other endpoints.
