Robbie Strickland created CASSANDRA-7252: --------------------------------------------
Summary: 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 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. 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)
