Duo Zhang commented on HBASE-20362:
-----------------------------------
The test disappears on the flaky board.
If no objections will apply the patch to branch-2.0+.
> TestMasterShutdown.testMasterShutdownBeforeStartingAnyRegionServer is flaky

> In the output for a failed running, we only have 'Before call to shutdown

> just ignore the exception.
