Brad Schoening updated CASSJAVA-98:
-----------------------------------
Summary: Replace DefaultPolicy warning message when contact points are from
more than one DC (was: Replace warning message when contact points are from
more than one DC)
> Replace DefaultPolicy warning message when contact points are from more than

> Key: CASSJAVA-98
> URL: https://issues.apache.org/jira/browse/CASSJAVA-98
> Project: Apache Cassandra Java driver
> Issue Type: Improvement
> Components: Core
> Reporter: Brad Schoening
> Priority: Low
>
> We get a lot of questions from users about this WARN level message in the
> Java driver 4.3+:
> {quote}You specified dc1 as the local DC, but some contact points are from a
> different DC: Node(...); please provide the correct local DC, or check your
> contact points
> {quote}
> but as [@Erick Ramirez|https://the-asf.slack.com/team/URU06R75L] explains on
> a [StackOverflow
> answer|https://stackoverflow.com/questions/75799274/how-are-quorum-reads-handled-when-the-java-driver-only-contacts-nodes-in-local-d]
> this topic, "The contact points do not have anything to do with replicas and
> consistency levels."
>
> This warning was added in 4.3, before cross-DC failover was re-introduced in
> release 4.10. Although I realize cross-DC failover is problematic, this
> message does not seem helpful or at the very least should be INFO instead of
> WARN.
> App 1 may run in DC1 and App 2 in DC2, but they can share the same contact
> lists and implement their own failover when necessary, but without needing to
> update contact points.
> It would be more reasonable to WARN when you've configured
> *advanced.load-balancing-policy.dc-failover.allow-for-local-consistency-levels*
> as True. Warning on the contact points specified doesn't seem right.
