Description
When event-processor goes into the ERROR state, admin should run a global INVALIDATE METADATA to recover it. This is expensive and will impact all workloads using Impala.
It's proposed in this thread that we should expose a way to restart the event-processor if admins are sure that it's not stale (e.g. after manually refreshing some tables):

Both SQL commands and WebUI will be helpful.
