Elliott Clark commented on HBASE-13366:
---------------------------------------
[~enis] take the following:
* RS1 has region A
* RS2 has read replica for A
* Client wants to Put to region A
* Master wants RS2 to open Region A
* RS1 is asked to close region A with knowledge that RS2 is going to open it.
* Client gets RegionMovedException from RS1 with extra info.
* RS2 still has the replica open and sees the request.
* Client now fails something that should be retired in short order
> Throw DoNotRetryIOException instead of read only IOException

> Currently, the read only region just throws an IOException to the clients who
> send write requests to it. This will cause the clients retry for configured
> times or until operation timeout.
> Changing this exception to DoNotRetryIOException will make the client failed
> fast.
> Suggestions are welcomed~ Thanks
