Apache Knox - Hadoop Open Source Code

Apache Knox

  • It is a system to extend the reach of Apache Hadoop services to users outside of a Hadoop cluster without reducing Hadoop Security.

  • It runs as a server, or a cluster of servers, providing centralized access to one or more Hadoop clusters.

  • It is designed as a reverse proxy

  • It is integrated with services such as Ambari, Hadoop Distributed File System, Templeton (HCatalog), Stargate (HBase), Oozie, Hive/JDBC, Yarn RM, Storm


  • Simplifies access: Extends Hadoop’s REST/HTTP services by encapsulating Kerberos to within the Cluster.

  • Enhances security: Exposes Hadoop’s REST/HTTP services without revealing network details, providing SSL out of the box.

  • Centralized control: Enforces REST API security centrally, routing requests to multiple Hadoop clusters.

  • Enterprise integration: Supports LDAP, Active Directory, SSO, SAML, and other authentication systems
