Hanisha Koneru updated HDFS-12810:
----------------------------------
Attachment: HDFS-12810.001.patch
Thanks for reporting the issue, [~virajith].
When {{capacityRemaining}} (or {{capacityUsed}}) is 0, it is not being passed
to the helper functions {{fmt_byte}} and {{fmt_percentage}} (in _dfs-dust.js_).
I'm not sure why this is happening.
As a workaround, if capacityRemaining (or capacityUsed) is 0, we assign it a
negative value -1. This will be converted back to 0 by the helper functions
_fmt_byte_ and _fmt_percentage_.
> Under "DFS Storage Types", the Namenode Web UI doesn't display the
> capacityRemaining correctly when it is 0.
