> While recovering the cluster from CASSANDRA-7949 (using the flag from CASSANDRA-6621) I had to use sstablesplit tool to split large sstables. Nodes were off while using this tool and only one sstablesplit instance was running, of course. 
> After splitting was done I have restarted the nodes and they all started compacting the data. All the nodes are logging the exceptions like this:

> It seems that scrubbing helps but scrubbing blocks the compactions.
