Jeff Jirsa commented on CASSANDRA-13041: ---------------------------------------- Is there a chicken-and-egg problem with CASSANDRA-12510 ? > Do not allow removal of a DC from system_auth replication settings if the DC > has active Cassandra instances > ----------------------------------------------------------------------------------------------------------- > > Key: CASSANDRA-13041 > URL: https://issues.apache.org/jira/browse/CASSANDRA-13041 > Project: Cassandra > Issue Type: Improvement > Components: Distributed Metadata > Reporter: Nachiket Patil > Assignee: Nachiket Patil > Priority: Minor > Fix For: 4.x > > Attachments: trunk.diff > > > I don’t believe it is ever correct to remove a DC from the system_auth > replication settings while there are nodes up in that DC. Cassandra should > not allow this change if there are hosts which are currently members of the > cluster in that DC, as any request which is routed to these hosts will meet > an unavailable. Also dropping the keyspace system_auth should not be allowed. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
