> Preemptive fast fail exception is a mechanism to prevent client threads from 
> blocking on talking to a unresponsive server.
> This was introduced in HBASE-6629.
> However, if a PFFE is thrown from an inner function (say locateRegionInMeta), 
> then the outer functions should not process this exception as a failure in 
> talking to the RS. We should just percolate this exception back to the client.
