stephbat updated HIVE-24218:
----------------------------
Component/s: CLI
> Drop table used by a materialized view
> --------------------------------------
>
> Key: HIVE-24218
> URL: https://issues.apache.org/jira/browse/HIVE-24218
> Project: Hive
> Issue Type: Bug
> Components: CLI, Metastore
> Affects Versions: 3.1.0
> Reporter: stephbat
> Priority: Major
>
> I have discovered that it's possible to drop a table used by a materialized view. When
I drop this table, the result is OK while I think this action should be refused. When I check
in the metastore database, I can see that the table has been partially deleted (ie : the reference
of the table still exists in TBLS and in MV_TABLES_USED). This introduces an inconsistency
in the metastore.
> Steps to reproduced :
> {code:java}
> jdbc:hive2://localhost.> use use ptest2_db_dev;
> No rows affected (0.067 seconds)
> 0: jdbc:hive2://localhost.> create table table_blocked (id string);
> No rows affected (0.97 seconds)
> 0: jdbc:hive2://localhost.> desc table_blocked;
> +-----------+------------+----------+
> | col_name | data_type | comment |

> | id | string | |
> +-----------+------------+----------+
> 1 row selected (0.171 seconds)
> 0: jdbc:hive2://localhost.> create materialized view table_blocked_mv as select *
from table_blocked;
