Tim Armstrong commented on IMPALA-6897:
---------------------------------------
I guess I don't understand why we'd include it in profiles if it's just a
global property of the system and not related to the actual files that the
query is scanning. Can't we just make a catalog server metric or something?
> Catalog server should flag tables with large number of small files

> Key: IMPALA-6897
> URL: https://issues.apache.org/jira/browse/IMPALA-6897
> 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".
