AntiEntropyService excluding nodes that are on version 0.7 or sooner
--------------------------------------------------------------------
Key: CASSANDRA-2768
URL: https://issues.apache.org/jira/browse/CASSANDRA-2768
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.8.0
Environment: 4 node environment --
Originally 0.7.6-2 with a Keyspace defined with RF=3
Upgraded all nodes ( 1 at a time ) to version 0.8.0: For each node, the node
was shut down, new version was turned on, using the existing data files /
directories and a nodetool repair was run.
Reporter: Sasha Dolgy
When I run nodetool repair on any of the nodes, the
/var/log/cassandra/system.log reports errors similar to:
INFO [manual-repair-1c6b33bc-ef14-4ec8-94f6-f1464ec8bdec] 2011-06-13
21:28:39,877 AntiEntropyService.java (line 177) Excluding /10.128.34.18 from
repair because it is on version 0.7 or sooner. You should consider updating
this node before running repair again.

The INFO message and subsequent ERROR message are logged for 2 nodes .. I
suspect that this is because RF=3.
nodetool ring shows that all nodes are up.
Client connections (read / write) are not having issues..
nodetool version on all nodes shows that each node is 0.8.0
At suggestion of some contributors, I have restarted each node and tried to run
a nodetool repair again ... the result is the same with the messages being
logged.
