[jira] [Created] (HIVE-22566) Drop table involved in materialized
view leaves the table in inconsistent state
Pablo Junge created HIVE-22566:
----------------------------------
Summary: 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
If you try dropping a table which is part of the definition of a created materialized view, the 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 dropped 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 ORCTBLPROPERTIES ('transactional'='true');
CREATE TABLE depts ( deptno INT, deptname VARCHAR(256), locationid INT)STORED AS ORCTBLPROPERTIES ('transactional'='true');
{code}
2) Create the VM:
{code:java}
CREATE MATERIALIZED VIEW mv1ASSELECT empid, deptname, hire_dateFROM 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}
0: jdbc:hive2://c1122-node2.squadron.support.> drop table emps;
INFO : Compiling command(queryId=hive_20191202200025_c13079d0-8695-4485-8a18-14804b8b014b): drop table emps

INFO : Executing command(queryId=hive_20191202200025_c13079d0-8695-4485-8a18-14804b8b014b): drop table emps

INFO : OK
No rows affected (16.949 seconds)
{code}
No issue displayed
5) List tables:
{code:java}
0: jdbc:hive2://c1122-node2.squadron.support.> show tables;
INFO : Compiling command(queryId=hive_20191202200125_ca12565b-1d4d-4433-a602-ecf685863413): show tables
INFO : Semantic Analysis Completed (retrial = false)
INFO : Returning Hive schema: Schema(fieldSchemas:[FieldSchema(name:tab_name, type:string, comment:from deserializer)], properties:null)
INFO : Completed compiling command(queryId=hive_20191202200125_ca12565b-1d4d-4433-a602-ecf685863413); Time taken: 0.041 seconds
INFO : Executing command(queryId=hive_20191202200125_ca12565b-1d4d-4433-a602-ecf685863413): show tables
INFO : Starting task [Stage-0:DDL] in serial mode
INFO : Completed executing command(queryId=hive_20191202200125_ca12565b-1d4d-4433-a602-ecf685863413); Time taken: 0.016 seconds
INFO : OK
+-----------+
| tab_name |
+-----------+
| depts |
| emps |
+-----------+
2 rows selected (0.08 seconds)
{code}
6) Now, from the backend-db point of view:
{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 | NULL | emps | MANAGED_TABLE |
| 83 | 16 | 83 | depts | MANAGED_TABLE |
| 84 | 16 | 84 | mv1 | MATERIALIZED_VIEW |
+--------+-------+-------+----------+-------------------+
3 rows in set (0.00 sec)
{code}
The table is left with NULL in SD_ID, making it not available.
7) From Metastore.log
{code:java}
