---------------------------------------
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}}.
