Jesus Camacho Rodriguez updated HIVE-18842:
-------------------------------------------
Description:
We should support defining a {{CLUSTERED ON/DISTRIBUTED ON/SORTED ON}}
specification for materialized views.
The syntax should be extended as follows:
{code:sql}
CREATE MATERIALIZED VIEW [IF NOT EXISTS] [db_name.]materialized_view_name
[COMMENT materialized_view_comment]
[PARTITIONED ON (col_name, ...)]
[CLUSTERED ON (col_name, ...) | ( [DISTRIBUTED ON (col_name, ...)] [SORTED ON
(col_name, ...)] ) ] -- NEW!
[
[ROW FORMAT row_format]
[STORED AS file_format]
| STORED BY 'storage.handler.class.name' [WITH SERDEPROPERTIES (...)]
]
[LOCATION hdfs_path]
[TBLPROPERTIES (property_name=property_value, ...)]
AS select_statement;
{code}
