Miklos Gergely resolved HIVE-24218. ----------------------------------- Resolution: Duplicate > 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, Hive, HiveServer2, Metastore > Affects Versions: 3.1.0 > Reporter: stephbat > Priority: Critical > > 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 inĀ 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; > 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) > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
