Hive offers a number of configuration settings related to performance, file layout and handling, and options to control SQL semantics. Depending on your cluster size and workloads, configure HiveServer2 memory, table locking behavior, and authentication for connections. See Configuring HiveServer2 for CDH for details about required configuration changes that you must perform.

The Hive metastore service, which stores the metadata for Hive tables and partitions, must also be configured. See Configuring the Hive Metastore for CDH for details about deployment modes, information about supported metastore databases, and specific configurations for MySQL, PostgreSQL, and Oracle.

To configure Hive to use the Amazon S3 filesystem for transient ETL jobs, see Configuring Transient Apache Hive ETL Jobs to Use the Amazon S3 Filesystem in CDH
