•Arun Murthy, from the Hadoop team at Yahoo! will introduce compendium of best practices for applications running on Apache Hadoop. In fact, we introduce the notion of a Grid Pattern which, similar to Design Pattern, represents a general reusable solution for applications running on the Grid. He will even cover the anti-patterns of applications running on the Apache Hadoop clusters. Arun will enumerate characteristics of well-behaved applications and provide guidance on appropriate uses of various features and capabilities of the Hadoop framework. It is largely prescriptive in its nature; a useful way to look at the presention is to understand that applications that follow, in spirit, the best practices prescribed here are very likely to be efficient, well-behaved in the multi-tenant environment of the Apache Hadoop clusters and unlikely to fall afoul of most policies and limits.
