> Affects Versions: Impala 2.9.0
> Reporter: Henry Robinson
> Assignee: Rahul Shivu Mahadev
> Priority: Major
> Labels: newbie, ramp-up

> Although we retain the histogram of fragment instance startup latencies, we don't record the identity of the most expensive instance, or the host it runs on. This would be helpful in diagnosing slow query start-up times.
