Component/s: Connectors / Hive
(was: Table SQL / Client)
(was: Table SQL / Runtime)
> Create view lost Time attribute in Hive Catalog
> -----------------------------------------------
>
> Key: FLINK-27641
> URL: https://issues.apache.org/jira/browse/FLINK-27641
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Hive
> Affects Versions: 1.12.3, 1.14.4
> Reporter: Robert Wu
> Priority: Minor
>
> Create table in hive catalog with the following sql state. :
>
> {code:java}
> CREATE TABLE user_score(
> username varchar,
> score varchar,
> proctime AS PROCTIME()
> ) with (
> 'connector'='datagen',
> 'rows-per-second'='2',
> 'fields.score.length'='2',
> 'fields.username.length'='2'
> );{code}
>
> We can get the description:
>
> {code:java}
> DESCRIBE user_score;
> +----------+-----------------------------+-------+-----+---------------+-----------+
> | name | type | null | key | extras |
> watermark |
> +----------+-----------------------------+-------+-----+---------------+-----------+
> | username | STRING | true | | |
> |
> | score | STRING | true | | |
> |
> | proctime | TIMESTAMP_LTZ(3) *PROCTIME* | false | | AS PROCTIME() |
> |
> +----------+-----------------------------+-------+-----+---------------+-----------+
> {code}
>
>
> However,view create in hive catalog will lost Time attribute in the proctime
> field:
>
> {code:java}
> create view view_score_hive_catalog as select * from user_score;{code}
>
> {code:java}
> DESCRIBE view_score_hive_catalog;
>
> +----------+------------------+-------+-----+--------+-----------+
> | name | type | null | key | extras | watermark |
> +----------+------------------+-------+-----+--------+-----------+
> | username | STRING | true | | | |
> | score | STRING | true | | | |
> | proctime | TIMESTAMP_LTZ(3) | false | | | |
> +----------+------------------+-------+-----+--------+-----------+
> {code}
>
>
> Otherwise,when we excute the same state. in default catalog, things are going
> to change:
> {code:java}
> Create view view_score_mem_catalog as select * from
> myhive.[hive_database].user_score;{code}
>
> {code:java}
> DESCRIBE view_score_mem_catalog;
> +----------+-----------------------------+-------+-----+--------+-----------+
> | name | type | null | key | extras | watermark |
> +----------+-----------------------------+-------+-----+--------+-----------+
> | username | STRING | true | | | |
> | score | STRING | true | | | |
> | proctime | TIMESTAMP_LTZ(3) *PROCTIME* | false | | | |
> +----------+-----------------------------+-------+-----+--------+-----------+
> {code}
