100intl/hadoop repository overview

#Apache Hadoop 2.6.0 Docker image

⁠Build the image

If you'd like to try directly from the Dockerfile you can build the image as:

docker build  -t 100intl/hadoop .

⁠Pull the image

The image 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.

docker pull 100intl/hadoop

⁠Start a container

In order to use the Docker image you have just build or pulled use:

Make sure that SELinux is disabled on the host. If you are using boot2docker you don't need to do anything.

docker run -it 100intl/hadoop /etc/bootstrap.sh -bash

⁠Testing

You can run one of the stock examples:

cd $HADOOP_PREFIX
# run the mapreduce
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar grep input output 'dfs[a-z.]+'

# check the output
bin/hdfs dfs -cat output/*

⁠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 this Bintray repo⁠. Enjoy.

⁠Automate everything

As we have mentioned previousely, a Docker file was created and released in the official Docker repository⁠
