------------------------------------------

             Summary: Upgrading Ambari Causes Alert Fields Not To Save Thresholds
                 Key: AMBARI-17202
                 URL: https://issues.apache.org/jira/browse/AMBARI-17202
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.2
            Reporter: Vitaly Brodetskyi
            Assignee: Vitaly Brodetskyi
            Priority: Critical
             Fix For: 2.4.0


When upgrading from earlier versions of Ambari, the alert definitions do not include some
of the new parameters / connection timeout values which were added to the alert definitions.
This is normally OK since the alert framework has sensible defaults of the values are not
specified.
However, it was observed on Ambari 2.2.2 that the web client wasn't able to properly render/save
the values.
STR:
Install Ambari 2.2.0
Upgrade to Ambari 2.2.2
You should now have alert definitions, such as DataNode Web UI, which do not have a connection_timeout
value.
Navigate to the DataNode Web UI alert definition page and notice that you are not able to
update and save the "Connection Timeout" property correctly.
