> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog
> Affects Versions: Impala 2.13.0
> Reporter: bharath v
> Priority: Major
> Labels: ramp-up, supportability

> Since Catalog has all the file metadata information available, it should help
> flag tables with large number of small files. This information can be
> propagated to the coordinators and should be reflected in the query profiles
> like how we do for "missing stats".
