How to install Hive Metastore in Kubernetes?

Question

I am working on a project on Kubernetes where I use Spark SQL to create tables and I would like to add partitions and schemas to an Hive Metastore. However, I did not found any proper documentation to install Hive Metastore on Kubernetes. Is it something possible knowing that I have already a PostGreSQL database installed? If yes, could you please help me with any official documentation?

Thanks in advance.

Hive on MR3 allows the user to run Metastore in a Pod on Kubernetes. The instruction may look complicated, but once the Pod is properly configured, it's easy to start Metastore on Kubernetes. You can also find the pre-built Docker image at Docker Hub. Helm chart is also provided.

The documentation assumes MySQL, but we have tested it with PostgreSQL as well.
