> 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.
