Ayush Saxena commented on HDFS-15130:
-------------------------------------
There is an ENUM for excess, but none for under replicated.
That has to be mathematically calculated only, that doesn’t make sense. There
won’t be any use case to do so,
For the excess, you may track the JIRA where it was added.
