> Hive ORC/Parquet write code path is same as data source v1 code path (FileFormatWriter). This JIRA is to add the support to write Hive ORC/Parquet bucketed table with hivehash. The change is to custom `bucketIdExpression` to use hivehash when the table is Hive bucketed table, and the Hive version is 1.x.y or 2.x.y.
>  
> This will allow us write Hive/Presto-compatible bucketed table for Hive 1 and 2.
