[jira] [Updated] (HIVE-14493) Partitioning support for materialized views

     [ https://issues.apache.org/jira/browse/HIVE-14493?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jesus Camacho Rodriguez updated HIVE-14493:
-------------------------------------------
    Description: 
We should support defining a partitioning specification for materialized views and that the results of the materialized view evaluation are stored meeting the partitioning spec. 

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, ...)] -- 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}
