Description John Sanda 2018-02-08 22:56:28 UTC 
Description of problem:
Hawkular Alerts has been packaged with Hawkular Alerts for the past few (maybe more) versions of OCP. Because Hawkular Alerts has never been supported and because of changes in future plans around Hawkular Metrics, it no longer makes sense to continue packaging Hawkular Alerts. It is a burden in that it creates extra support and maintenance work. When we need to upgrade a common library, e.g., the Cassandra driver, we cannot perform the upgrade solely in Hawkular Metrics. We also have to perform the upgrade in Hawkular Alerts. This is because of some class loading issues with the way things are packaged inside of the WildFly application server. This creates a lot of extra work in terms of productization builds. 

We can reduce the deployment unit from a complex EAR file to a much more simple WAR file that only includes Hawkular Metrics. This simplifies iterative development and testing as well. There is a good bit of custom configuration done to WildFly for Hawkular Alerts. That will no longer be needed.

Issue is not fixed, it is changed to ON_QA by errata, change back to MODIFIED

The following war packages are still in hawkular-metrics.ear
hawkular-alerts-action-elasticsearch.war
hawkular-alerts-action-email.war
hawkular-alerts-action-webhook.war
hawkular-alerts.war

Imges:
metrics-cassandra-v3.9.2-1
metrics-hawkular-metrics-v3.9.2-1
metrics-heapster-v3.9.2-1
Comment 11 Junqi Zhao 2018-03-23 09:10:44 UTC 
checked in metrics-hawkular-metrics/images/v3.9.14-1, only hawkular-metrics.war is left now, and sanity testing is passed.

This defect can move to ON_QA now
