Description
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 :
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; No rows affected (18.055 seconds) 0: jdbc:hive2://localhost.> desc table_blocked_mv; +-----------+------------+----------+ | col_name | data_type | comment | +-----------+------------+----------+ | id | string | | +-----------+------------+----------+ 1 row selected (0.316 seconds) 0: jdbc:hive2://localhost.> drop table table_blocked; No rows affected (10.803 seconds) 0: jdbc:hive2://localhost.> desc table_blocked_mv; +-----------+------------+----------+ | col_name | data_type | comment | +-----------+------------+----------+ | id | string | | +-----------+------------+----------+ 1 row selected (0.222 seconds) 0: jdbc:hive2://localhost.> desc table_blocked; Error: Error while compiling statement: FAILED: SemanticException Unable to fetch table table_blocked. null (state=42000,code=40000) 0: jdbc:hive2://localhost.> select * from table_blocked_mv; Error: Error while compiling statement: FAILED: SemanticException Table ptest2_db_dev.table_blocked not found when trying to obtain it to check masking/filtering policies (state=42000,code=40000)
