Hivemetastore in synapse analytics

Question

Is there a way that we can connect Synapse to Hivemetastore with out a Database. I am looking for any documentation that would help here.

Answer 1

Hello Michael M,

As per the below documentation, Currently, Azure Synapse Analytics only supports Azure SQL Database and Azure Database for MySQL as an external Hive Metastore.

If you don’t have a database, you need to consider setting up "Azure SQL database" or "Azure Database for MySQL" to connect Azure Synapse Analytics with a Hive Metastore.

Reference document:
https://learn.microsoft.com/en-us/azure/synapse-analytics/spark/apache-spark-external-metastore#set-up-linked-service-to-hive-metastore

Known limitations

• Synapse Studio object explorer will continue to show objects in managed Synapse metastore instead of the external HMS.
• SQL <-> Spark synchronization doesn't work when using external HMS.
• Only Azure SQL Database and Azure Database for MySQL are supported as external Hive Metastore database. Only SQL authorization is supported.
• Currently Spark only works on external Hive tables and non-transactional/non-ACID managed Hive tables. It doesn't support Hive ACID/transactional tables.
• Apache Ranger integration is not supported.

I hope this answers your quesiton.
