PRESENTATIONS: 

1. The Collector - A Tool to Have Multi-Writer Appends into HDFS
by Bryan Duxbury, Software Engineer at Rapleaf

Bryan will cover The Collector, a tool built by Rapleaf that facilitates multi-writer appends into Hadoop Distributed Filesystem.  This talk will detail why this is an important workflow component, along with the performance characteristics and some gotchas surrounding the implementation of such a system.

Stefan will describe an in-production system that processes millions of events, producing trend alerts and reports, using Hadoop and Katta, a distributed indexing system.


3. Debugging and Tuning Map-Reduce Applications
by Arun C Murthy, Principal Engineer at Yahoo! and Member of Apache Hadoop PMC

Arun will cover simple home-made remedies for peering into the Hadoop Map-Reduce framework as it crunches your data.  This wide-ranging discussion will cover topics such as using debuggers/profilers on your applications, using Map-Reduce Counters, other simple ways to tune your applications, and how to avoid common pitfalls.
