> 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):
> https://lists.apache.org/thread/5mw8jd5hgz7yycz9h2pxvqj101k0j47m
> Both SQL commands and WebUI will be helpful.
