Subject [jira] [Commented] (HDFS-12810) Under "DFS Storage Types", the Namenode Web UI doesn't display the capacityRemaining correctly when it is 0.

    [ https://issues.apache.org/jira/browse/HDFS-12810?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16255214#comment-16255214

Virajith Jalaparti commented on HDFS-12810:
-------------------------------------------

Thanks for posting a fix [~hanishakoneru]. While this fix solves this particular case, is
there a reason why the value of 0 "gets lost" from {{dfshealth.js}} to {{dfshealth.html}}
({{b.capacityRemaining}} has a value of 0 in {{dfshealth.js}} but {{value.capacityRemaining}}
doesn't retain this value in {{dfshealth.html}}) ? I suspect this might be something to do
with the call to {{render()}} in {{dfshealth.js}}.

> When the {{capacityRemaining}} for a StorageType is 0, the Namenode's Web UI displays
an empty string ("()") instead of "0 (0%)".
