Sergey Shelukhin commented on HIVE-17126:
-----------------------------------------
Sounds like a DataNucleus issue to me (assuming it supports Maria DB), or at
least the lack of functionality (assuming it doesn't). You might want to find
out which one :)
Also, there's an ORM-free, SQL-based implementation of the entire metastore in
the works in HIVE-14870. That is Oracle-specific, but some (or at least I ;) )
believe it should be database agnostic. It might also be of use, if there isn't
an easy solution with DataNucleus.

> Hive Metastore is incompatible with MariaDB 10.x
> ------------------------------------------------
>
> 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.
