This error message indicates that there is an issue with the database table used by Hive. Specifically, it seems that the table does not exist or cannot be accessed.

The error occurs in the method org.datanucleus.store.rdbms.table.AbstractTable.exists(AbstractTable.java:606), which is part of the DataNucleus framework used by Hive to manage database operations.

To fix this issue, you can try the following steps:

1. Check if the database table exists: Verify that the table referenced in the error message exists in the database. You can use a database management tool or command-line interface to connect to the database and check the table's existence.

2. Verify database connectivity: Ensure that Hive is properly configured to connect to the database. Check the Hive configuration files (hive-site.xml, core-site.xml) to ensure that the database connection parameters are correctly specified.

3. Check database permissions: Make sure that the user running Hive has the necessary permissions to access the database and the table. Check the database's user and table permissions to ensure they are correctly set.

4. Restart Hive: If you made any configuration changes, it's recommended to restart Hive to apply the changes. This can be done by restarting the Hive service or the Hive server.

5. Update Hive version: The error message also mentions that Hive-on-MR is deprecated in Hive 2. It's recommended to consider using a different execution engine, such as Spark or Tez, or using Hive 1.X releases. If possible, you can upgrade to a newer version of Hive that supports the recommended execution engines.

If the issue persists after following these steps, you may need to consult the Hive documentation or seek assistance from the Hive community or your database administrator for further troubleshooting
