This is the documentation for CDH 4.7.1. Documentation for other versions is available at Cloudera Documentation.

Installing and Using HCatalog

Apache 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 it for REST access and for MapReduce and Pig access. For Sqoop, see the section on Sqoop-HCatalog integration in the Sqoop User Guide.

HCatalog ships as a component within CDH4, even though later upstream versions have been merged with Hive.

For more information, see the HCatalog documentation.
