Following on the success of our Hadoop 2.3.0, 2.4.0 and 2.4.1 Docker image, the feedbacks and requests we have received and aligning with the Hadoop release cycle, we have released an Apache Hadoop 2.5.0 Docker image – same as the previous version this is available as a trusted and automated build on the official Docker registry.
Please note that beside this Hadoop image, we have released and maintain a pseudo-distributed and fully distributed Hadoop Docker image provisioned with Apache Ambari. As they are provisioned with Ambari you have the option to change, add and remove Hadoop components using cluster blueprints.
Also we are happy to let you know that this release of Apache Hadoop contains a few of SequenceIQ’s open source contributions and fixes around YARN schedulers. We are working on an SLA enforcer for Hadoop – very soon to be open sourced – and part of that work we are contributing back to the community. Also there is a major contribution of ours coming in the next release of Hadoop – 2.6.0. Stay tuned and follow us on LinkedIn, Twitter or Facebook.
Build the image
In case you’d like to try directly from the Dockerfile you can build the image as:

As it is also released as an official Docker image from Docker’s automated build repository – you can always pull or refer the image when launching containers.
Start a container
In order to use the Docker image you have just build or pulled use:

Hadoop native libraries, build, Bintray, etc
The Hadoop build process is no easy task – requires lots of libraries and their right version, protobuf, etc and takes some time – we have simplified all these, made the build and released a 64b version of Hadoop nativelibs on our Bintray repo. Enjoy.
