Duo Zhang commented on HBASE-21017:
-----------------------------------
I think we need to fix this.
The flaky TestEnable table is related, where we call assign on an already
onlined region. It should be rejected but actually not. The RS will ignore the
open request so the TRSP will hang. In a local run, it could be fixed by
regionServerReport, where we will check the online regions. But in the failing
runs, there maybe a race that we update the state to OPEN, without waking up
the procedure, and then the TRSP will hang there forever.
I think we should find out where is the race, but another problem is that, we
should not allow assigning a region which has already been online.
