In order to maximize performance, developers need to understand the inner workings of the MapReduce execution framework and how they are affected by various configuration parameters and MR design patterns. The talk will illustrate the underlying mechanics of job and task execution, including the map side sort/spill, th

Inside Yahoo Labs, S4 i
Amazon Elastic MapReduce Announces Support for Cluster Compute and Cluster GPU Instances
We are excited to announce the immediate ability for Amazon Elastic MapReduce customers to take advantage of Cluster Compute (cc1.4xlarge) and Cluster GPU (cg1.4xlarge) instances, allowing you to combine Hadoop’s massively parallelized architecture with high performance computing. You can focus on developing HPC applications and Elastic MapReduce will handle workload parallelization, node configur
