Note: this is the master branch - for a particular Hadoop version always check the related branch
A few weeks ago we released an Apache Hadoop 2.3 Docker image - this quickly become the most popular Hadoop image in the Docker registry.
Following the success of our previous Hadoop Docker images, the feedback and feature requests we received, we aligned with the Hadoop release cycle, so we have released an Apache Hadoop 2.7.1 Docker image - same as the previous version, it's available as a trusted and automated build on the official Docker registry.
FYI: All the former Hadoop releases (2.3, 2.4.0, 2.4.1, 2.5.0, 2.5.1, 2.5.2, 2.6.0) are available in the GitHub branches or our Docker Registry - check the tags.
这个版本修改Dockerfile时区为中国区。考虑到中国网络下载下列文件会非常的慢，所以把所有文件全部改为自行提供，而不是通过curl的方式调用，因此需要提供几个文件在当前目录下：
可以分别另寻渠道自行下载
添加docker-compose.yml文件，添加logs映射，快速启动
If you'd like to try directly from the Dockerfile you can build the image as:
docker build -t sequenceiq/hadoop-docker:2.7.1 .
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 sequenceiq/hadoop-docker:2.7.1
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 sequenceiq/hadoop-docker:2.7.1 /etc/bootstrap.sh -bash
Start with docker-compose
docker-compose up -d
You can run one of the stock examples:
cd $HADOOP_PREFIX
# run the mapreduce
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.1.jar grep input output 'dfs[a-z.]+'
# check the output
bin/hdfs dfs -cat output/*
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.
As we have mentioned previousely, a Docker file was created and released in the official Docker repository
