> Impala with External frontend hit a DCHECK in
> RuntimeProfile::EventSequence::Start(int64_t start_time_ns) because frontend
> report remote_submit_time that is more than 3ns ahead of Coordinator time.
> This can happen if there is a clock skew between Frontend node and Impala
> Coordinator node.
> Impala Coordinator should validate remote_submit_time against its own clock.
