> Project: HBase
> Issue Type: Task
> Components: documentation
> Reporter: Jean-Daniel Cryans
>
> The following questions were asked on IRC and I couldn't find a good source
> of info in the online book (so I had to answer them, sad I know):
> bq. when a region server goes down, 1) do any queries get affected which are
> using that region server, if they do what happens to the transactions 2) how
> long does it take to switch over to another region server?
> Brief answers:
> To Q1:
> The queries get retried (I'm not sure if we have a chapter that describes how
> that works, might be worth adding however bad it currently is).
> To Q2:
> ZK session timeout + split time + assignment/replay time.
