The following hash index is distributed explicitly on l_partkey and stored explicitly in row-hash order on l_partkey:

     CREATE HASH INDEX line_hidx_2 (l_partkey) ON lineitem
     BY (l_partkey) 
     ORDER BY HASH (l_partkey);

This creates an index that is equivalent in structure to the following join index.

     CREATE JOIN INDEX line_jidx_2 AS
      SELECT (l_partkey), (l_orderkey, lineitem.ROWID) 
      FROM lineitem
     PRIMARY INDEX (l_partkey);
