I believe that the underlying problem is with the hive metastore canary timeout. Do the following to change it and remove the databases: Instructions
Increase the Cloudera Manager timeout value for reading the Hive MetaStore by navigating to, Hive service > Configuration > Service-Wide > Monitoring > Service Monitor Client Config Overrides.
Modify the value of "hive.metastore.client.socket.timeout" from 20 to 1800.
Manually clear the database used by the Hive MetaStore. The following gives an example of SQL queries to clear the Oracle database for the Hive Metastore [other databases (MySQL/PostgreSQL) are similar].
