> Project: Hadoop HDFS
> Issue Type: Improvement

>
> 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.
