> HBASE-12035 moved keeping table enabled/disabled state from ZooKeeper into 
> hbase:meta.  When we retry operations on the client, we check table state in 
> order to return a specific message if the table is disabled.  This means that 
> in master we will be going back to meta for every retry, even if a region's 
> location has not changed.  This is going to cause performance issues when a 
> cluster is already loaded, ie. in cases where regionservers may be returning 
> CallQueueTooBigException.
