Review request for Ambari, Dmytro Grinenko, Dmitro Lisnichenko, Jonathan 
Hurley, and Nate Cole.


Summary (updated)
-----------------

Ambari calculates stack downgrade as ABORTED under incorrect conditions. UI 
shows 'Downgrade paused' and button to resume downgrade even when progress is 
happening


Bugs: AMBARI-15569
    https://issues.apache.org/jira/browse/AMBARI-15569


Repository: ambari


Description
-------

*STR:*
1. Install Ambari 2.2.0
2. Upgrade stack from HDP-2.2.4 to HDP-2.3.2
3. At finalize step, choose downgrade option
4. Introduce failures in some clients such as Zookeeper and Yarn.

In this case, the status of some tasks are marked as ABORTED.
This causes the overall status of the Downgrade to be ABORTED, and hence the UI 
shows an incorrect message and button.
Technically, the Downgrade is still progressing, yet the UI shows "Downgrade 
paused" and a button to "Resume Downgrade"

This means that the calculations of the stages is incorrect.
