>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: hdfs
>    Affects Versions: 3.0.0-alpha2
>            Reporter: Sarah Victor
>            Assignee: Sarah Victor
>            Priority: Trivial

> On the dfshealth.html#tab-datanode web page to monitor health of Hadoop nodes 
> (hadoop-hdfs-project/hadoop-hdfs/src/main/webapps/hdfs/dfshealth.html)
> (1) The Capacity column reports the node capacity but is sorted by another 
> value that is not reported (ie) the % Capacity Used. It will be good to name 
> the column heading as "Capacity Used [%]" and report both the Capacity Used 
> and the Capacity Used %
> (2) The Block Pool Used column reports the block pools used but is sorted by 
> the % Block Pool Used, It will be good to name the column heading as Block 
> Pool Used [%]
> (3) The "Last contact" column is more easily understood if we call it "Last 
> Heartbeat". Adding the measurement unit [secs] to the header makes it more 
> easily understood.
> (3) Adding the measurement unit [mins] to the "Last Block Report" header 
> makes it more easily understood.
