>             Project: IMPALA
>          Issue Type: Test
>          Components: Infrastructure
>    Affects Versions: Impala 2.12.0
>            Reporter: Tim Armstrong
>            Priority: Major
>
> We only have a single very basic table with mixed formats that I can see. It 
> would be good to have a larger table that includes parquet, so we can 
> exercise some of the more interesting memory reservation code paths. I think 
> the requirements are:
> * Files of at least multiple MBs in size
> * Includes Parquet and at least one row-based format
> * Ideally a mix of different file and partition sizes
> We want queries that exercise "interesting" code paths:
> * Many columns returned: select * from table.
> * Single column returned
> * No columns returned - e.g. select count(*)
> * Selective scan with predicates
