Configuring Hive high availability

The Apache Hive service has multiple, associated components. The active Hive components are Hive Metastore and HiveServer2. You can configure high availability for the Hive service in HDP 2.2 or later by running two or more of each of those components. The relational database that backs the Hive Metastore itself should also be made highly available using best practices defined for the database system in use and should be done after consultation with your in-house DBA.
