      Description

      Currently Hive+Parquet doesn't support it. It should include at least basic type promotions short->int->bigint, float->double etc, that are already supported for other file formats.

      There were similar effort (Hive-6784) but was not committed. This JIRA is to address the same in different way with little (no) performance impact.
