---------------------------------
hi ruanhui
I design an UT in the HBASE-28139.patch. View the test case of
TestRaceBetweenSCPAndDTPOnPreDisable, i reproduce the scenario. When SCP run on
SERVER_CRASH_ASSIGN and DTP run on DISABLE_TABLE_PREPARE, DTP haven't changed
table state to disabling. In the scenario, SCP will create TRSP successful. At
that time, due to DTP hold xlock, TRSP could not be executed.
> Disable table may hang when SCP create TRSP but DTP didn't set tableState to
> disabling
