> ---------------------------------------------------------------------------
>
> Key: SPARK-14396
> URL: https://issues.apache.org/jira/browse/SPARK-14396
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Xiao Li
>
> Because the concept of partitioning is associated with physical tables, we disable all the supports of partitioned views, which are defined in the following three commands in [Hive DDL Manual](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-Create/Drop/AlterView):
> {noformat}
> ALTER VIEW view DROP [IF EXISTS] PARTITION spec1[, PARTITION spec2, ...];
> ALTER VIEW view ADD [IF NOT EXISTS] PARTITION spec;
> CREATE VIEW [IF NOT EXISTS] [db_name.]view_name [(column_name [COMMENT column_comment], ...) ]
> [COMMENT view_comment]
> [TBLPROPERTIES (property_name = property_value, ...)]
> AS SELECT ...;
> {noformat}
>
> An exception is thrown when users issue any of these three DDL commands.
