> {{EntityGroupFSTimelineStore}} now depends on an RM being up and running; the
> configuration pointing to it. This is a new change, and impacts testing where
> you have historically been able to test without an RM running.
> The sole purpose of the probe is to automatically determine if an app is
> running; it falls back to "unknown" if not. If the RM connection was
> optional, the "unknown" codepath could be called directly, relying on age of
> file as a metric of completion
> Options
> # add a flag to disable RM connect
> # skip automatically if RM not defined/set to 0.0.0.0
> # disable retries on yarn client IPC; if it fails, tag app as unknown.
