Amitanand Aiyer updated HBASE-7517:
-----------------------------------
Description:
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.
> Preemptive fast fail exception should not be processed multiple times in the
> stack
