[jira] [Created] (CASSANDRA-2979) Skip system table when repair
Skip system table when repair
-----------------------------
Key: CASSANDRA-2979
URL: https://issues.apache.org/jira/browse/CASSANDRA-2979
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 0.8.2
Reporter: Norman Maurer
>From ml:
When I run nodetool repair on a node on my 3-node cluster, I see 3 messages like the following:
INFO [manual-repair-6d9a617f-c496-4744-9002-a56909b83d5b] 2011-07-30 18:50:28,464 AntiEntropyService.java (line 636) No neighbors to repair with for system on (0,56713727820156410577229101238628035242]: manual-repair-6d9a617f-c496-4744-9002-a56909b83d5b completed.
Granted, there's no data on these machines yet. Is this normal?
And the answer:
You can discard those. This is saying it cannot repair the system keyspace
(table used internally). It turns those aren't replicated and thus don't need
to be repaired. We should probably update the code to skip trying to
repair the system table but in the meantime this is harmless.

I could have sworn we already skip system table on repair. Maybe that is only in trunk?

Norman Maurer commented on CASSANDRA-2979:
------------------------------------------
I just had a quick look again and it seems like it also tries to repair the system table in 0.8.x. Maybe I just miss something here so it will never try todo so...
About the patch.. I was not sure if the right place is StorageService or NodeProbe to handle this here. So I'm open for suggestions and to provide another patch if necessary..
