@Kevin Vasko I believe you are asking for SSO, Single Sign On. SSO and Knox integration works. http://hortonworks.com/blog/hadoop-security-today-and-tomorrow/ Perimeter level Security With Apache Knox
Apache Hadoop has Kerberos for authentication. However, some organizations require integration with their enterprise identity management and Single Sign-On (SSO) solutions. Hortonworks created Apache Knox Gateway (Apache Knox) to provide Hadoop cluster security at the perimeter for REST/HTTP requests and to enable the integration of enterprise identity-management solutions. Apache Knox provides integration with corporate identity systems such as LDAP, Active Directory (AD) and will also integrate with SAML based SSO and other SSO systems. Apache Knox also protects a Hadoop cluster by hiding its network topology to eliminate the leak of network internals. A network firewall may be configured to deny all direct access to a Hadoop cluster and accept only the connections coming from the Apache Knox Gateway over HTTP. These measures dramatically reduce the attack vector. Finally, Apache Knox promotes the use of REST/HTTP for Hadoop access. REST is proven, scalable, and provides client interoperability across languages, operating systems, and computing devices. By using Hadoop REST/HTTP APIs through Knox, clients do not need a local Hadoop installation.
