--------------------------------

             Summary: Write Hive ORC/Parquet bucketed table with hive murmur3hash (for Hive 3)
                 Key: SPARK-32711
                 URL: https://issues.apache.org/jira/browse/SPARK-32711
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Cheng Su


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 hive murmur3hash. The change is to custom `bucketIdExpression` to use hive murmur3hash when the table is Hive bucketed table, and the Hive version is 3.x.y.

 

This will allow us write Hive/Presto-compatible bucketed table for Hive 3.
