Description

We need to fix the following issues on YARN web-UI:

• Remove the "Note" column from the application list. When a failure happens, this "Note" spoils the table layout.
• When the Application is still not running, the Tracking UI should be title "UNASSIGNED", for some reason it is titled "ApplicationMaster" but (correctly) links to "#".
• The per-application page has all the RM related information like version, start-time etc. Must be some accidental change by one of the patches.
• The diagnostics for a failed app on the per-application page don't retain new lines and wrap'em around - looks hard to read.
