> Key: HIVE-17126
> URL: https://issues.apache.org/jira/browse/HIVE-17126
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 1.2.0, 1.1.0, 2.0.0
> Reporter: Eric Yang
>
> MariaDB 10.x is commonly used for cheap RDBMS high availability. Hive usage
> of Datanucleus is currently preventing Hive Metastore to use MariaDB 10.x as
> highly available metastore. Datanucleus generate SQL statements that are not
> parsable by MariaDB 10.x when dropping Hive table or database schema.
> Without MariaDB HA setup, the SQL statement problem also exists for metastore
> interaction with MariaDB 10.x.
