One year ago we released the first milestone release of the Spring for Apache Hadoop version 2.0 project, just in time for SpringOne 2GX 2013. To keep up the tradition, we are pleased to announce the first milestone release of Spring for Apache Hadoop 2.1, just in time for SpringOne 2GX 2014 in Dallas, TX. The release is now available in the Spring IO repository

Main changes for the 2.1.0.M1 release:

• Added support for append mode in store writers
• Enhancements for kerberos configuration for secured cluster access
• Support for container grouping and clustering in Spring YARN, which brings functionality for running multiple container types, a new REST API and an improved application model with new client side commands and a command line shell.
• Starting with this version we support Hadoop 2.0 APIs but no longer provide backwards compatibility with older Hadoop v1 distributions.

We provide support for the following distributions:

• Apache Hadoop 2.2.0 (default)
• Apache Hadoop 2.4.1 (hadoop24)
• Apache Hadoop 2.5.0 (hadoop25)
• Pivotal HD 2.0 (phd20)
• Cloudera CDH5 (cdh5)
• Hortonworks HDP 2.1 (hdp21)

Come and check out our two Spring Hadoop related sessions tomorrow Tuesday 9/9 at SpringOne2GX.
