[jira] Created: (CASSANDRA-988) DatacenterEndPointSnitch does not
work with RackAwareStrategy
DatacenterEndPointSnitch does not work with RackAwareStrategy
-------------------------------------------------------------
Key: CASSANDRA-988
URL: https://issues.apache.org/jira/browse/CASSANDRA-988
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.6, 0.6.1, 0.6.2, 0.7, 0.8
Reporter: Erick Tryzelaar
RackAwareStrategy explicitly tests for the snitch to be a subclass of EndPointSnitch, but DatacenterEndPointSnitch doesn't subclass from it, but rather AbstractEndPointSnitch.

[jira] Updated: (CASSANDRA-988) DatacenterEndPointSnitch does not
work with RackAwareStrategy
Posted by "Erick Tryzelaar (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-988?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Erick Tryzelaar updated CASSANDRA-988:
--------------------------------------
Attachment: 0001-Rename-AbstractEndpointSnitch-to-AbstractEndPointSni.patch
0002-Fix-RackAwareStrategy-to-work-with-DatacenterEndPoin.patch
These depend on #984 being committed. The first patch is a simple rename of AbstractEndpointSnitch to AbstractEndPointSnitch to be consistent with the other locator files. The second changes the RackAwareStrategy to test for subclasses of AbstractEndPointSnitch instead of EndPointSnitch. Not sure if there's a more appropriate way to fix this though.

It looks like things aren't completely fixed yet. I'm now getting this assertion on a couple of my nodes:

-------------------------------------------
That exception seems to be coming from a race condition. It occurred when I started the 10 nodes all at the same time. I repeated this while starting one node at a time, and they all came up cleanly.
