Apache HCatalog is a module in Apache Hive that enables non-Hive scripts to access Hive tables. HCatalog provides table data access for CDH components such as Pig 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 without having to worry about re-defining the input schemas, or caring about or duplicating the data’s location.
On Oracle Big Data Appliance(BDA) V2.2.* and higher HCatalog is installed by default. Hue uses Beeswax for queries and for accessing the metastore instead of HCatalog.
This document provides steps on how to enable HCatalog in HUE for accessing the Hive tables from the Pig Editor.
