> 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.
