[jira] [Commented] (CASSANDRA-7252) RingCache cannot be configured to use local DC only

The rest, however, should be split into separate tickets. RingCache cannot be configured to use local DC only --- Key: CASSANDRA-7252 URL: https://issues.apache.org/jira/browse/CASSANDRA-7252 Project: Cassandra Issue Type: Bug Components: Hadoop Reporter: Robbie Strickland Assignee: Robbie Strickland Labels: patch Fix For: 2.0.10, 2.1.1 Attachments: cassandra-2.0.7-7252-2.txt, cassandra-2.0.7-7252.txt RingCache always calls describe_ring, returning the entire cluster. Considering it's used in the context of writing from Hadoop (which is typically in a multi-DC configuration), this is often not desirable behavior. In some cases there may be high-latency connections between the analytics DC and other DCs. I am attaching a patch that adds an optional config value to tell RingCache to use local nodes only, in which case it calls describe_local_ring instead. It also adds helpful failed host information to IOExceptions thrown in AbstractColumnFamilyOutputFormat.createAuthenticatedClient, CqlRecordWriter, and ColumnFamilyRecordWriter. This allows a user to more easily solve related connectivity issues. -- This message was sent by Atlassian JIRA (v6.2#6252)
