Hello folks, Could you please help review the design doc attached to https://issues.apache.org/jira/browse/AMBARI-12697 ?
It's a UI feature I am proposing that displays all the upgrade and downgrade attempts done against the cluster. So that customers can review the upgrade/downgrade history much the same as how they may review all the background requests that Ambari server handles. (Users can see the background requests list via the "ops" link at the top of the page, right besides the cluster name). Please let me know of your comments. If all is good, I will start coding it. Thanks Di.
