PropertyFileEndPointSnitch can only be used once per configuration
------------------------------------------------------------------
Key: CASSANDRA-1448
URL: https://issues.apache.org/jira/browse/CASSANDRA-1448
Project: Cassandra
Issue Type: Bug
Components: Contrib
Affects Versions: 0.7 beta 1, 0.6.5, 0.6.4
Environment: Debian
Reporter: David Viner
When a user configures a node to have more than one keyspace, and two keyspaces
uses PropertyFileEndPointSnitch as the EndpointSnitch, Cassandra throws an
error on startup saying:
ERROR [main] 2010-08-30 23:55:23,402 DatabaseDescriptor.java (line 536) Fatal
error: Invalid endpointsnitch class
org.apache.cassandra.locator.PropertyFileEndPointSnitch null
This appears to be directly tied to the use of MBeanServer.registerMBean(). If
more than one instance is tied to the mbean server, it will return an
InstanceAlreadyExistsException. Since this appears to be a valid exception,
but causes no errors in operation, the snitch should catch it and continue on.
Patch file to follow.
