Lei (Eddy) Xu commented on HDFS-6729:
-------------------------------------
Hi, [~aw]. We have cases users to upgrade RAM and/or add disks etc., which only
takes a short amount of time (e.g., 10 minutes downtime). It might not need to
report missing data on this DN if the users are certain that the DN will come
back shortly.
> Support maintenance mode for DN
