Subject Waiting for repair requests to: []
Date Tue, 31 Aug 2010 22:20:54 GMT
Just wanted to check on the operation of nodetool repair. I'm running the trunk nightly from 2010-08-26_13-52-57

I ran it this morning against one node in a 4 node cluster, on each node in the cluster I
saw this in the log

INFO [manual-repair-6516fb70-d654-4fe2-815b-5d3a6b77106d] 2010-09-01 09:45:13,891 AntiEntropyService.java
(line 803) Waiting for repair requests to: []

In the comments for https://issues.apache.org/jira/browse/CASSANDRA-1432 Stu said that this
line indicates the cluster thinks the RF is 1, however I've double checked using the cassandra-cli
and it's 3 for this keyspace.  

I turned logging up to DEBUG and these look like the messages associated with running the
repair...

According to code in AntiEntrophyService around line 804 I should see another INFO message
is the repair requests were sent successfully. After 10 minutes there were no messages in
the log from either that thread or the AntiEntrophyService logger. 

Is there anything else I can do to check that AES is working or is the log message really
saying that there is nothing to do?

Thanks
Aaron
