Cloudera Videos Hadoop World 2011: Hadoop Gateway – Cluster Virtualization Framework

Access to Hadoop clusters through dedicated portal nodes (typically located behind firewalls and performing user authentication and authorization) can have several drawbacks -- as shared multitenant resources they can create contention among users and increase the maintenance overhead for cluster administrators. This session will discuss the Gateway system, a cluster virtualization framework that provides multiple benefits: seamless access from users’ workplace computers through corporate firewalls; the ability to failover to active clusters for scheduled or unscheduled downtime, as well as the ability to redirect traffic to other clusters during upgrades; and user access to clusters running different versions of Hadoop.
