Description

Description:

Generated 'AM Node Web UI' link can not be interpreted by RM.

Reproduction

• Run MapReduce pi example job
• Open the app details page
• Click on AM Node Web UI
• Page won't load

Fix:

The problem is the URL finishes with a '/' so RM can not open the node page.
To fix this we should modify the UI code to generate the URL without the last '/' char
