Subject [jira] Created: (HDFS-1086) Percentage bar in dfsnodelist.jsp shows wrong values

Percentage bar in dfsnodelist.jsp shows wrong values
----------------------------------------------------

                 Key: HDFS-1086
                 URL: https://issues.apache.org/jira/browse/HDFS-1086
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.20.2
            Reporter: Kurt Huwig


dfsnodelist.jsp shows a bar for each node which indicated how much of the filesystem is used.
The HTML code is 

<table border="1px" width="100px"><tr><td cellspacing="0" class="perc_filled"
width="2%"></td><td cellspacing="0" class="perc_nonfilled" width="98%"></td></tr>

The corresponding CSS in /static/hadoop.css reads like this:

div#dfsnodetable td, div#dfsnodetable th, div#dfstable td {
	padding-left : 10px;
	padding-right : 10px;
}

This padding results in wrong bars, as the 10 pixels are added to the bar which I verified
with firebug.

The proper fix would be to use an enclosing div for the bar, so that the style for the rest
of the table - which needs the padding - does not apply to the bars.
