I am happy to announce that the first milestone release (1.0.0.M1) for Spring for Apache Hadoop project is available and talk about some of the work we have been doing over the last few months. Part of the Spring Data umbrella, Spring for Apache Hadoop provides support for developing applications based on Apache Hadoop technologies by leveraging the capabilities of the Spring ecosystem. Whether one is writing stand-alone, vanilla MapReduce applications, interacting with data from multiple data stores across the enterprise, or coordinating a complex workflow of HDFS, Pig, or Hive jobs, or…

As datacenters virtualize more and more workloads, it becomes important to understand the potential impact on the Java servers that may be running your applications. At SpringOne 2GX 2011, Ben Corrie provided a thorough overview of Java memory management, how things work differently in virtual environments and what you can do about it to avoid problems. This includes a practical introduction to Elastic Memory for Java (EM4J) that is a feature of the VMware vFabric platform.

Many thanks to InfoQ for coming to Chicago to record so many of the fantastic SpringOne 2GX presentations.
