> Cleanup HIVEQUERYRESULTFILEFORMAT handling

>                 Key: HIVE-23699
>                 URL: https://issues.apache.org/jira/browse/HIVE-23699
>             Project: Hive
>          Issue Type: Improvement
>          Components: HiveServer2
>    Affects Versions: 4.0.0
>            Reporter: John Sherman
>            Assignee: John Sherman
>            Priority: Major
>
> HIVEQUERYRESULTFILEFORMAT format handling has grown over the years and has 
> become somewhat messy code wise in SemanticAnalyzer and TaskCompiler. There 
> are special cases where the HIVEQUERYRESULTFILEFORMAT setting gets changed at 
> runtime that may cause issues if a user changes execution.engines between 
> queries and probably other corner cases.
