Description

The NameNode HA health check alert must be rewritten as a SCRIPT based alert since it requires advanced logic and knowledge of all NameNode states to make the correct alert state determination.

This will also involve extending alert definitions to include the ability to ignore the host reporting the alert, essentially collapsing all alert instances into a single entry regardless of originating host.
