Noticed this while running randomwalk against 1.8.0-SNAPSHOT. The 
monitor's aggregated log messages were just filled with things like the 
following:

Failed to execute Repo, tid=76367ba00e847e10
	ThriftTableOperationException(tableId:null, tableName:ctt_000, 
op:CREATE, type:EXISTS, description:null)

Now, this is happening because of the concurrent module renaming tests, 
but is this really a warning that we want to propagate to the monitor? 
Everything is just fine and dandy in the system. Doesn't seem like it 
really needs to be a warning. Similarly, the following also falls into 
the same bucket.

Cannot move tables to a new namespace by renaming. The namespace for 
nspc_000.ctt_002 does not match ctt_001

Thoughts before I open an issue to change them?
