Mingliang Liu updated HDFS-10306:
---------------------------------
Attachment: HDFS-10306.000.patch
Thanks [~walter.k.su] for suggesting separating this code out of [HDFS-10284],
which was to address
{{o.a.h.hdfs.server.blockmanagement.TestBlockManagerSafeMode.testCheckSafeMode}}
unit test intermittent failure.
The v0 patch was from the v1 patch of [HDFS-10284]. Please review.
> SafeModeMonitor should not leave safe mode if name system is starting active

> This is a follow-up of [HDFS-10192].
> The {{BlockManagerSafeMode$SafeModeMonitor#canLeave90}} is not checking the
> {{namesystem#inTransitionToActive()}}, while it should. According to the fix
> of [HDFS-10192], we should add this check to prevent the {{smmthread}} from
> calling {{leaveSafeMode()}} too early.
