> 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.
