Vivek Ganesan commented on HDFS-4926:
-------------------------------------

No new tests were introduced because only cosmetic issues were fixed. No 
functionality changes.

To test the fix, following steps were followed:

1. Hadoop dist tar was created from the patch.
2. Started DFS (start-dfs.sh)
3. Opened http://localhost:50070 and navigated to live nodes list link to 
verify the fix in a single-node environment
                
> namenode webserver's page has a tooltip that is inconsistent with the 
> datanode HTML link

> At http://localhost:50070/dfsnodelist.jsp?whatNodes=LIVE, there is a list of 
> Live datanodes in a table.  In the Node column, there is a link to each node. 
> If you hover your cursor over one of the links, it shows the IP address and 
> port number of the datanode. However, actual link is the hostname instead of 
> the IP. 
> Suggest that the tooltip reflect the actual url that the web browser would go 
> to if the link is selected.
