> Example can be seen in HBASE-7250.
> Server A has region, region is moved to B, B dies, region starts moving to C.
> Client goes to A, A sends him to B, B is dead so he refreshes meta (which has A), it
goes to A, which sends it to B, ...
> These retries are unnecessary.
> Overall, I wonder if retry policy should be replaced by timeout policy, preferably configurable
on per-request basis by client? That sounds like a reasonable feature to me, so if the timeout
is set to high values retries will not be exhausted due to situations like this.
