Subject ERROR Compaction Interrupted
Date Mon, 01 Jun 2015 18:31:04 GMT
Hi everyone,
I am running C* 2.0.9 without vnodes and RF=2. Recently while repairing, rebalancing the cluster
I encountered one instance of this(just one on one node):

ERROR CompactionExecutor: <https://logentries.com/app/9f95dbd4#>55472 CassandraDaemon.uncaughtException
- Exception in thread Thread[CompactionExecutor: <https://logentries.com/app/9f95dbd4#>55472,1,main]

After looking up a bit on the mailing list archives etc I understand that this might mean
data corruption and I plan to take the node offline and replace it with a new one but still
wanted to see if anyone can throw some light here about me missing out on something.
Also, if this is a case of corrupted SST should I be concerned about it getting replicated
and take care of it on the replication too.

Thanks
