Pablo Junge updated HIVE-22566:
-------------------------------
Status: Open (was: Patch Available)
> Drop table involved in materialized view leaves the table in inconsistent
> state
> -------------------------------------------------------------------------------
>
> Key: HIVE-22566
> URL: https://issues.apache.org/jira/browse/HIVE-22566
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 3.1.0
> Reporter: Pablo Junge
> Assignee: Pablo Junge
> Priority: Minor
> Fix For: 4.0.0
>
> Attachments: HIVE-22566.02.patch, HIVE-22566.patch
>
>
> If you try dropping a table which is part of the definition of a created
> materialized view, the table is not dropped, which is the desired state as it
> is part of the materialized view.
> However, there was a "drop" call to the table, so it tried to drop it but did
> not succeed, leaving it in an inconsistent state.
>
> Repro:
> -------
> 1) Create tables:
>
> {code:java}
> CREATE TABLE emps ( empid INT, deptno INT, name VARCHAR(256), salary
> FLOAT, hire_date TIMESTAMP)STORED AS ORC TBLPROPERTIES
> ('transactional'='true');
> CREATE TABLE depts ( deptno INT, deptname VARCHAR(256), locationid
> INT)STORED AS ORC TBLPROPERTIES ('transactional'='true');
> {code}
>
> 2) Create the VM:
>
> {code:java}
> CREATE MATERIALIZED VIEW mv1 AS SELECT empid, deptname, hire_date FROM emps
> JOIN depts ON (emps.deptno = depts.deptno) WHERE hire_date >= '2016-01-01';
> {code}
>
> 3) Following is in backend database at this point:
>
> {code:java}
> mysql> select TBL_ID, DB_ID, SD_ID, TBL_NAME, TBL_TYPE from TBLS where
> DB_ID=16;
> +--------+-------+-------+----------+-------------------+
> | TBL_ID | DB_ID | SD_ID | TBL_NAME | TBL_TYPE |

> | 81 | 16 | 81 | emps | MANAGED_TABLE |
> | 83 | 16 | 83 | depts | MANAGED_TABLE |
> | 84 | 16 | 84 | mv1 | MATERIALIZED_VIEW |
> +--------+-------+-------+----------+-------------------+
> 3 rows in set (0.00 sec)
> {code}
>
> 4) Let's drop the 'emps' table:
>
> {code:java}
