[GitHub] drill issue #976: DRILL-5797: Choose parquet reader from read columns

    Drill follows SQL rules and is case insensitive. If case sensitivity has 
snuck in somewhere (perhaps due to the use of `equals()` rather than 
`equalsIgnorCase()` or the use of a case-sensitive map), then we should fix 
that.
    
    Note also that column aliases should not be visible to the Parquet reader.
