> 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]:

> 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.
