---------------------------------------------------------------------
I was thinking how to fix this. Think jira should fix (1) starting from trunk
down to 2.7.4.
For (2) there was an easier fix for HDFS-9034, just to swap 2 lines in
{{HeartbeatManager.register()}}, that is first do {{updateHeartbeatState()}},
then {{addDatanode()}}. The former will reset everything to 0 in DND, including
nonDfsUsed and the latter will be adding 0 then. This would avoid breaking
followup jiras. We should just add the swapping in branch-2.7 patch here.

> Non-dfsUsed will be doubled on dead node re-registration in branch-2.7.
