Subject [jira] [Created] (CASSANDRA-13970) Remove PFS compatibility mode from GPFS
Date Thu, 19 Oct 2017 15:19:00 GMT
Paulo Motta created CASSANDRA-13970:
---------------------------------------

             Summary: Remove PFS compatibility mode from GPFS
                 Key: CASSANDRA-13970
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13970
             Project: Cassandra
          Issue Type: Task
          Components: Configuration
            Reporter: Paulo Motta
            Assignee: Paulo Motta
            Priority: Minor


{{GossipingPropertyFileSnitch}} (GPFS) has a compatibility mode which fallbacks to {{PropertyFileSnitch}}
(PFS) to fetch rack/dc info from {{conf/cassandra-rackdc.properties}} when a node info is
not found in Gossip.

The problem is that we supply a default {{conf/cassandra-rackdc.properties}}, which is loaded
in clusters (as shown in the log below) and may affect ring layout before gossip settles potentially
leading to issues such CASSANDRA-13948.

{code:none}
INFO  [main] 2017-10-12 14:39:32,928 GossipingPropertyFileSnitch.java:64 - Loaded cassandra-topology.properties
for compatibility
{code}

I see 2 options to preven this from causing similar problems in the future:
a) Remove PFS compatibility mode
a) Move {{conf/cassandra-rackdc.properties}} to {{examples}} or {{conf/examples}}.
