Subject [jira] [Commented] (HDFS-10235) [NN UI] Last contact for Live Nodes should be relative time
Date Mon, 04 Apr 2016 11:43:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15223974#comment-15223974
] 

Brahma Reddy Battula commented on HDFS-10235:
---------------------------------------------

 {{lastContact}} is given as seconds itself from the NameNode. It is being converted to absolute
time stamp in UI side.
 
Now if we convert that to msec, it will be in multiples of 1000 itself.
 So, its better to be in seconds itself. as this is only for user/admin to see. Not for any
metrics.

> Last contact for Live Nodes should be relative time and we can keep absolute date for
Dead Nodes. Relative time will be more convenient to know the last contact , we no need to
extra maths here.
