Spring for Apache Hadoop 2.1.0.M1 Released

Engineering | Thomas Risberg | September 08, 2014 | ...

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.

Join us at the Spring Data birds-of-a-feather session @springone2gx #s2gx

Are you ready for SpringOne? It's almost here!

A popular part of SpringOne are the birds-of-a-feather sessions. Different groups get together to talk about different aspects of Spring, Groovy, and Grails. This year, they are scheduled for Tuesday night, September 9th, starting at 9pm. (When do they end? When everyone finally leaves!)

They are indeed popular. Last year I sat in on the Spring Framework one and enjoyed the close, unscripted discussions (not lectures). You should think about carving out some time for that!

This year, we have a new session planned: Spring Data.

If you aren't aware…

This Week in Spring - September 2nd, 2014

Engineering | Josh Long | September 03, 2014 | ...

Welcome to another installment of This Week in Spring!

This is the last installment of TWiS before SpringOne2GX 2014 kicks off next week! I, personally, am very excited! I can't wait to see you all there. This is going to be so much fun. So, let's get on to it!

Spring guides make it easier to jump to core content

Engineering | Greg L. Turnquist | September 02, 2014 | ...

If you remember last year, we rolled out a powerful new website built top-to-bottom with Spring. It was fresh, new, and loaded with gobs of getting started guides.

Since then, the feedback has been overwhelmingly positive. We've had record traffic with a large portion visiting the guides. So what's new?

We recently added the ability to hide/show the build steps. Many people expressed the desire to skip project setup steps and instead jump to the core content. We listened and responded.

After reading over a guide, do you need Gradle or Maven build steps? No problem! Just click on the…

This Week in Spring - August 26th, 2014

Engineering | Josh Long | August 26, 2014 | ...

Holy cats! Can you believe how close we are to SpringOne2GX? Last year we made a huge splash with the announcements of Spring Boot and Spring XD, both of which have recently hit 1.0 releases. I happen to know the next level looks like, and you're going to want to see it. Register now if you haven't already!

Building a RESTful quotation service with Spring

Engineering | Greg L. Turnquist | August 21, 2014 | ...

I was recently made aware that a public API we were using for one of our guides contained objectionable material. After confirming this, I immediately responded that we would pick another source. Wishing to avoid such an issue in the future, I decided the best solution was to build our own RESTful quote service. So I decided to use the best tools to do so, the Spring stack, and was able to migrate the very next day.

Picking your tools

To kick things off, I made a check list of what I knew would be the right tools for the job of creating a RESTful web service.

Preview Spring Security WebSocket Support

Engineering | Rob Winch | August 21, 2014 | ...

[callout title=Updated Dec 11 2014]Although originally about Spring Security 4.0.0.M2, the blog has been updated to reflect improvements found in Spring Security 4.0 RC1.[/callout]


Previously, an application could use Spring Security to perform authentication in a WebSocket application. This worked because the Principal of an HttpServletRequest will be propagated to the WebSocket Session.

The problem is that authorization was limited to handshake. This means that once the connection was made, there was no way to provide any granularity to authorization of the WebSocket application…

This Week in Spring-19th August 2014

Engineering | Josh Long | August 19, 2014 | ...

Welcome to another installment of This Week in Spring! It's a few weeks before SpringOne2GX 2014, already! Time sure flies when you're having fun! The beginning of 2015 will mark the 4th year of This Week in Spring, and it's more exciting every week! I'm hoping to see as many of you as possible at SpringOne2GX 2014. This is sure to be an amazing event.

Anyway, with that out of the way, let's get on to this week's roundup!

  1. Spring Security lead Rob Winch just announced Spring Security 4.0.0.M2, which

provides a lot of great features, including improved Security-aware testing support, Spring Data integration, support for websocket security, and ties into the nascent Spring Session projet that was derived from the work for this release. Check it out! Rob also announced Spring Security 3.2.5 and 3.1.7

This Week in Spring - August 12th, 2014

Engineering | Josh Long | August 12, 2014 | ...

Welcome to another installment of This Week in Spring. We've got a lot of cool stuff happening and, as you might imagine, the entire team is abuzz in preparation for SpringOne2GX 2014, coming in just a few short weeks! If you haven't registered, now's the time to do so!

  1. Spring Security lead and all-around sleepless ninja Rob Winch has just announced that Spring MVC Test HtmlUnit 1.0.0.M2 has been released. This is an awesome release if you're trying to unit test real pages with Spring MVC
  • Spring Boot 1.1.5 has just been released. The new release mainly addresses a few issues and is a recommended upgrade for all users.
  • I really enjoyed this blog, ¿Qué es Spring Framework?, which tries to explain what the fundamental value of Spring is. Largely, the (Spanish language) article explains that Spring handles the lifecycle for objects in a consistent way. It's easy to plug in various frameworks, software, around the edges when the fundamental life-cycle is handled. I would point out that this post uses Spring…
