Committed to trunk. Thanks @smarthanwang for your contributions.
BTW, Would you like to fix checkstyle about method length is 156 lines is
over 150 limit for BlockManager, IMO this is historical issue, we should file
another issue to refactor it.

> I have backport the nice feature HDFS-16043 to our internal branch, it works
> well in our testing cluster.
> I think it's better to make the fields *_deleteBlockLockTimeMs_* and
> *_deleteBlockUnlockIntervalTimeMs_* configurable, so that we can control the
> lock and unlock duration.
> {code:java}
> private final long deleteBlockLockTimeMs = 500;
> private final long deleteBlockUnlockIntervalTimeMs = 100;{code}
> And we should set the default value smaller to avoid blocking other requests
> long time when deleting some large directories.
