stephbat created HIVE-24218: ------------------------------- Summary: 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: Hive Affects Versions: 3.1.0 Reporter: stephbat
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.
