Hadoop World 2011: Hadoop Gateway – Cluster Virtualization Framework

Date

Wednesday, November 9th, 2011

Description

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.
