[jira] Updated: (CASSANDRA-1448) PropertyFileEndPointSnitch can only be used once per configuration

["David Viner (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-1448?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

David Viner updated CASSANDRA-1448:
-----------------------------------

    Attachment: patch-for-mbean-error.patch

This patch is against the 0.6.4 source tag.  However, it should apply equally to the 0.6.5 tree.

The 0.7.x tree does not need this patch, since that code appears to have taken out the mbean class entirely.

> 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.
