> In case the primary node is down (the node where schema modifications are 
> send to), a timeout exception occurs internally in Hector. Upon such an 
> exception it will retry the request, until the host is finally marked as down 
> and withdrawn from the pool of available hosts. In the meantime, lots of 
> stacktraces and error messages drop by while this doesn't indicate a real 
> serous issue: when the first node is stopped in a 3-node cluster (with RF 3 
> and Quorum R/W) for maintenance these errors already appear. So in this case 
> they are definitely verbose.
> Unfortunately, this verbose logging takes place in the HConnectionManager of 
> hector, which can only be changed by patching Hector.
