--------------------------------------------
Summary: Ambari calculates stack downgrade as ABORTED under
incorrect conditions. UI shows "Downgrade paused" and button to resume
downgrade even when progress is hapenning
Key: AMBARI-15569
URL: https://issues.apache.org/jira/browse/AMBARI-15569
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.2.0
Reporter: Alejandro Fernandez
Assignee: Alejandro Fernandez
Fix For: 2.2.2
*STR:*
# Install Ambari 2.2.0
# Upgrade stack from HDP-2.2.4 to HDP-2.3.2
# At finalize step, choose downgrade option
# 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.
