Suggestions required for HDFS-4926 (namenode webserver's page has a tooltip that is inconsistent with the datanode HTML link)

[Vivek Ganesan]

Hi,

We have 3 options (actually view points) laid out for resolution of 
HDFS-4926 <https://issues.apache.org/jira/browse/HDFS-4926>.

(See 
https://issues.apache.org/jira/browse/HDFS-4926?focusedCommentId=13707219&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13707219)

Summarizing the options here.

Option -1 : Tool tip should be consistent with the HTML Link (view point 
of the issue reporter)
Option -2 : It's okay to provide supplementary useful information in the 
tool tip (view point of a reviewer)
Option -3 : Add new column to show data transfer port. Add new column to 
show http port.  Change the tooltip of link to show ip address only.

Please review these options and vote.

Thank you.

Regards,
Vivek Ganesan.
