We are pleased to announce the Spring for Apache Hadoop 2.2 GA release.

The most important changes/enhancements in the Spring for Apache Hadoop 2.2 version are:

• Improvements to the HDFS writer to support syncable writes and a new timeout option
• Improvements in the HBase support - adding PUT and DELETE to HbaseTemplate
• Add support for Pivotal HD 3.0
• Update Cloudera CDH 5 to use version 5.3.3
• Update Hortonworks HDP 2.2 version to 2.2.4.0
• Update Kite SDK to version 1.0
• Update Spring project versions to the latest

We continue…

As you might have gathered from my Java EE 7 blog post, we are planning for a Spring Framework 5.0 generation with a 2016 availability horizon. We'll be tracking JDK 9's release candidates then since one of our key themes is comprehensive JDK 9 support.

The feature planning for Spring 5 is still in the works. We are going to present a more in-depth plan at SpringOne this year, so stay tuned! Nevertheless, I would like to take this opportunity to reach out to you for feedback about our intended system requirements:

We will definitely raise our minimum to JDK 8+. This is a prerequisite since it…

Welcome to another installment of This Week in Spring! What a week! This week I'm in Kansas City for the 6,000+-strong developer conference of a single company's developers and then it's back to New York City for QCon NYC where I'll be talking up building cloud-native applications with Spring Boot and Spring Cloud. If you're in either place be sure to reach out to me and let's talk shop (Spring, and, optionally, in Kansas City, BBQ..)

• Spring co-founder and project lead Juergen Hoeller put together two must-read posts this week: the first looks at Java 8 and Spring 4 adoption. ALSO, much, much, much more importantly: HE MENTIONED THIS WEEK IN SPRING :D #WIN.
• Juergen also posted is one of my favorite in years, a brutally honest look at the Java EE 7 landscape and the depressing lack of (big-vendor) supported implementations options for production-supported Java EE containers. You know, the man has a point..
• The amazing Dr. Pollack (see above!) announced Spring XD 1.2 RC1. The new release is packed with lots of new stuff including an Apache Ambari plugin to package and deploy Spring XD into production, new analytics, new features and performance improvements for the Apache Kafka support, improved HA configuration for RabbitMQ, Sqoop metastore support, and a lot…

For security reasons, browsers prohibit AJAX calls to resources residing outside the current origin. For example, as you're checking your bank account in one tab, you could have the evil.com website in another tab. The scripts from evil.com shouldn’t be able to make AJAX requests to your bank API (withdrawing money from your account!) using your credentials.

Cross-origin resource sharing (CORS) is a W3C specification implemented by most browsers that allows you to specify in a flexible way what kind of cross domain requests are authorized, instead of using some less secured and less powerful…

Note that there's a follow-up blog post about Spring 5 system requirements. You might want to start there if you're primarily interested in the Spring 5 planning process.

In our quest for Java EE integration, we're trying to actively embrace the latest generation of specifications such as JPA, Bean Validation and of course the Servlet and JMS APIs. As of Spring 4, we're supporting the Java EE 6 and 7 level of specifications side by side. We would like to raise it to the EE 7+ level (JPA 2.1, Bean Validation 1.1, and in particular Servlet 3.1 and JMS 2.0) soon but are facing a fundamental problem: the lack of EE 7 platform…

Spring Boot 1.2.4 has been released and is available now from repo.spring.io and Maven Central.

We’re pleased to announce a second milestone release of Spring Statemachine 1.0.0.M2.

With this milestone we focused on features in regions and pseudostates. Regions provide more sophisticated functionality for a parallel execution of a states machines and pseudostates will bring more functionality for working with initial, terminate, history, choice, fork and join states.

One might ask what is a region and how it works with a state machine. A state machine is a specialization of a region where orthogonal regions are composed of a multiple independent state machines. This is a difficult…

We’re pleased to announce the first version of the Apache Ambari plugin for Spring XD.

Ambari is a cluster provisioning tool to install and manage various Apache projects like HDFS, YARN, Zookeeper or Kafka. Ambari has a concept of a stack definition which is used by both Pivotal and Hortonworks. The stack definition is usually made up of components supported by the maintainer.

This Ambari integration adds support for provisioning Spring XD with Pivotal HD 3.0 and Hortonworks HDP 2.2.

Spring XD is not part of the main Ambari distribution for PHD or HDP. However, it is easy to extend an…
