Kihwal Lee commented on HDFS-11180:
-----------------------------------
+1 for the patch.
I am not sure whether it is worth mentioning the correctness of the value in
the release note. For most metrics uses, if not all, the values won't be
practically no more "inaccurate" than before.
> Intermittent deadlock in NameNode when failover happens.
