YARN Over MR1 - An Operational Win presented by Karthik Kambatla

YARN is the new resource management and execution framework of Apache Hadoop. This talk provides an architectural overview of YARN and its key components. It makes a case for migrating to YARN, particularly from MapReduce v1, for improved scalability and cluster utilization as well as multi-tenancy. The talk also goes through a few operational aspects of running YARN and concludes with an update on key features currently under development.


Karthik Kambatla is a Software Engineer at Cloudera, Apache Hadoop Committer, and a PhD student. He works primarily on scheduling and resource management in the Hadoop ecosystem.

      Thanks David, I'm viewing the stream for the first time and agree with what you're saying. I'll look into getting rid of them for the future.

      Thank you, Siobhain. On the positive side, it was easy to see the screen this time. I don't know if someone moved that "speaker spot" so it didn't reflect up and wash out the screen, or made some other adjustment, but whatever was done, it worked. Thanks for helping me avoid the 405 this evening!
