Ming Ma commented on HDFS-7877:
-------------------------------

Thanks Allen for pointing out. We didn't know about HDFS-6729 at all. Let me check out the
approach in that jira and we can combine the effort.

> This requirement came up during the design for HDFS-7541. Given this feature is mostly
independent of upgrade domain feature, it is better to track it under a separate jira. The
design and draft patch will be available soon.
