Chengwei Wang updated HDFS-16500:
---------------------------------
Description:
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 fileds 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.
