Guanghao Zhang commented on HBASE-22163:
----------------------------------------
Now TRSP didn't guarantee that the region will finally be on the target server.
Is it useful to warmup region? And as the normal TRSP will check the region
state in regionnode lock. Maybe we should move warmup to TRSP inside?
> May send a warmup rpc for a splited parent region
