> Wrong info about Impala dedicated executore

> Issue Type: Bug

> Reporter: Alex Rodoni

> The following is not correct.
> "Then, you specify that the other hosts act as executors but not
> coordinators. These hosts do not communicate with the statestored daemon or
> process the final result sets from queries. You cannot connect to these hosts
> through clients such as impala-shell or business intelligence tools."
> executor still communicates with statestore for other topics (membership,
> admission control, etc.) The only part it doesn't get from statestore is the
> metadata topic.
