> On our testing cluster, we observe a race condition:
> 1. A regionServerReport request is built
> 2. A TRSP is scheduled to reopen the region
> 3. The region is closed at RS side
> 4. The OpenRegionProcedure is created
> 5. The regionServerReport generated at step 1 is executed, and we find that
> the region is opened on the RS, so we update the region state to OPEN.
> 6. The OpenRegionProcedure notices that the region has already been in the
> OPEN state so gives up and finishes.
> 7. The TRSP finishes.
> 8. The region is recorded as OPEN on the RS but actually not, and can not
> recover unless we use HBCK2.
