Kihwal Lee commented on HDFS-9279:
----------------------------------
The jira was originally to exclude "live" decommissioned nodes from stat, but
it seems decommissioning nodes are excluded as well.
> Decomissioned capacity should not be considered for configured/used capacity

> Capacity of a decommissioned node is being accounted as configured and used
> capacity metrics. This gives incorrect perception of cluster usage.
> Once a node is decommissioned, its capacity should be considered similar to a
> dead node.
