HWKMETRICS-514 we introduced the usage of an infinispan cache as a method of coordination while applying schema updates. We needed to ensure only a single instance of hawkular-metrics would be apply schema updates. This was put in place particularly for OpenShift deployments where multiple instances of hawkular-metrics could be deployed concurrently. We have encountered some bugs in the version of JGroups that is used, and the ISPN cache has subsequently been problematic.
The purpose of this ticket is to altogether remove applying schema updates from the hawkular-metrics web app. Schema updates can be a separate concern that can be applied through a standalone installer.
