Support List as a conversion class for ARRAY

    XMLWordPrintableJSON

    Details

      Description

      Currently we don't support List as a conversion class in the new type system. However, there are multiple reasons why we should support this conversion:
      1) Hive uses List as the default for representing arrays e.g. in functions.
      2) The new Expression DSL supports converting lists to array literals already.
      3) The list interface is essential for Java users and part of many structured types.
      4) We need to represent lists in ListView for aggregate functions.
