Sarah Victor created HDFS-11825:
-----------------------------------
Summary: 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
Reporter: 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.
