Description

When repairing a node, the following exception was thrown two times:

ERROR [AntiEntropyStage:2] 2011-09-23 23:00:24,016 AbstractCassandraDaemon.java (line 139) Fatal exception in thread Thread[AntiEntropyStage:2,5,main]
java.lang.AssertionError
        at org.apache.cassandra.service.AntiEntropyService.rendezvous(AntiEntropyService.java:170)
        at org.apache.cassandra.service.AntiEntropyService.access$100(AntiEntropyService.java:90)

        at java.lang.Thread.run(Thread.java:662)

No other errors occurred on the node. From peeking at the code, this assertion appears to simply check if an existing repair session could be found. Interestingly, the repair did continue to run after this as evidenced by several other AntiEntropyService entires in the log.

8 node ring with an RF of 3, if that matters at all. No other nodes in the ring threw exceptions.
