Andrew Purtell commented on HBASE-6877:
---------------------------------------
Reissuing requests to the other daughter when a split is detected makes sense.
Minor issue with the patch is by dropping "actual" in method names and
variables, the result seems to read better.
> Coprocessor exec result is incorrect when region is in splitting

> When we execute the coprocessor, we will called HTable#getStartKeysInRange
> first and get the Keys to exec coprocessor,
> if then some regions are split before execCoprocessor RPC, the Keys are
> something wrong now, and the result we get is not integrated,
> for example:
> parent region is split into daughter region A and daughter region B,
> we executed coprocessor on the parent region, but the result data is only
> daughter region A or daughter region B
