This Hive tutorial describes how to configure Hive Metastore to MySQL. Hive stores its metadata (schema-related information, partitioning information, etc.) into the database, Hive is shipped with the Derby database. Derby is an embedded database backed by a local disk.

Derby is a single-threaded database that doesn’t allow multiple connections, it is not production-ready. In this tutorial, we will change the Metastore of Hive to MySQL.

What is Hive?

Apache Hive is a data warehouse on the top of Hadoop. Using Hive we can run ad-hoc queries for the analysis of data.

Hive saves us from writing complex Map-Reduce jobs, rather than that we can submit merely SQL queries. Hive converts SQL queries into MapReduce job and submits the same to the cluster.

Download MySQL connector (mysql-connector-java-5.1.35-bin.jar) and copy it into the $HIVE_HOME/lib directory
Note: $HIVE_HOME refers hive installation directory

iii. Edit / Create configuration file hive-site.xml

Add following entries in the hive-site.xml (present in $HIVE_HOME/conf)
