Installing and Using HCatalog

As of CDH 5, HCatalog is part of Apache Hive.

HCatalog provides table data access for CDH components such as Pig, Sqoop, and MapReduce. Table definitions are maintained in the Hive metastore, which HCatalog requires. HCatalog makes the same table information available to Hive, Pig, MapReduce, and REST clients. This page explains how to install and configure HCatalog for REST access and for MapReduce and Pig access. For Sqoop, see the section on Sqoop-HCatalog integration in the Sqoop User Guide.

For more information, see the HCatalog documentation.
