> High level description of node blacklisting, from IMPALA-8339:
> {quote}
> This patch adds the concept of a blacklist of executors to the
> coordinator, which removes executors from consideration for query
> scheduling. Blacklisting decisions are local to a given coordinator
> and are not included in statestore updates.
> The intention is to allow coordinators to be more aggressive about
> deciding that an exeutor is unhealthy or unavailable, to minimize
> failed queries in environments where cluster membership may be more
> variable, rather than having to wait on the statestore heartbeat
> mechanism to decide that the executor is down.
