-----------------------------------
Assignee: Sarah Victor
> Make dfshealth datanode information more readable
> -------------------------------------------------
>
> Key: HDFS-11825
> URL: https://issues.apache.org/jira/browse/HDFS-11825
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs
> Affects Versions: 3.0.0-alpha2
> Reporter: Sarah Victor
> Assignee: Sarah Victor
> Priority: Trivial
> Attachments: HADOOP-11825.1.patch
>
>
> 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.
