--------------------------------
Assignee: Bridget Bevens
> Document supported/unsupported hive functions
> ---------------------------------------------
>
> Key: DRILL-4750
> URL: https://issues.apache.org/jira/browse/DRILL-4750
> Project: Apache Drill
> Issue Type: Bug
> Components: Documentation
> Reporter: Rahul Challapalli
> Assignee: Bridget Bevens
>
> From our documentation it is not clear that Drill supports using hive
> functions natively. We should document all the supported hive functions. Few
> things to consider :
> 1. Drill does not support any hive functions which return unsupported
> data types (List, Map etc)
> 2. DATE and TIMESTAMP representations are incompatible between hive and
> drill. Some hive functions involving date and timestamp will work on data in
> a hive table, but will not work on non-hive data. Similarly some drill
> functions involving date and timestamp functions will work on non-hive data
> but will not work on hive data (could throw an error or report wrong data)
