Haohui Mai commented on HDFS-8816:
----------------------------------
Thanks [~raviprak] for the reviews. The v3 patch addresses the comments.
bq. At a lower zoom, the capacity becomes indented awkwardly. Also, there's no
indication of %ge in the capacity.
The v3 patch should fix the issue. I noticed that there's no percentage in the
previous UI and now the UI use different color to indicate the percentage.
Maybe we can file a new jira to add precise percentage if you think it is
helpful?
bq. With DIFP "Failed Volumes" would be very useful to have. Is there some
other place in the UI we can get that information?
The information should be available through the "DataNode Volume Failures" tab.
bq. Although I don't particularly care for the "Non DFS Used" myself, could you
please confirm you meant to remove it?
The information is now presented as a popup of the capacity bar.
bq. If I had a timestamp there, it would make it a lot easier for me to grep
through logs.
Good point. The v3 patch shows the timestamp.
