Chapter 2. Using HDP for Metadata Services (HCatalog)

Hortonworks Data Platform deploys Apache HCatalog to manage the metadata services for your Hadoop cluster.

Apache HCatalog is a table and storage management service for data created using Apache Hadoop. This includes:

  • Providing a shared schema and data type mechanism.

  • Providing a table abstraction so that users need not be concerned with where or how their data is stored.

  • Providing interoperability across data processing tools such as Pig, MapReduce, and Hive.
