Jimmy Xiang commented on HBASE-9161:
------------------------------------
After the test is done, in the final block, the region is onlined so that we
can disable/delete the table. Right after we online the region, the opening
fake ZK event kicks in and moves the region to OPENING state. Therefore, the
table can't be deleted, so the test hangs. We need to make sure the ZK event
is processed before we online/offline the region and disable/delete the table.
