Hadoop Docker项目
https://github.com/sequenceiq/hadoop-docker
sequenceiq提供2.3, 2.4.0, 2.4.1, 2.5.0版本的Hadoop，只需把下面2.5.0换成你需要的就可以
可以下载下来自己编译
docker build -t sequenceiq/hadoop-docker:2.5.0 .
可以直接下载
docker pull sequenceiq/hadoop-docker:2.5.0
运行方法
docker run -i -t sequenceiq/hadoop-docker:2.5.0 /etc/bootstrap.sh -bash
测试运行
cd $HADOOP_PREFIX #进入Hadoop目录
bin/hadoop fs -ls #查看hdfs目录
bin/hadoop fs -mkdir wordcountinput #创建目录
bin/hadoop fs -ls #查看hdfs目录
bin/hadoop fs -put etc/hadoop/core-site.xml /wordcountinput #上传文件
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.5.0.jar wordcount /wordcountinput /wordcountoutput
bin/hadoop fs -cat /wordcountoutput/* #view result
官方测试例子
cd $HADOOP_PREFIX
# run the mapreduce
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.5.0.jar grep input output 'dfs[a-z.]+'
# check the output
bin/hdfs dfs -cat output/*
将Hadoop在后台运行
后台运行Docker，需要加上 -d 参数
set hadoop port 50010 50070 to you outer server
docker run -d -p 50010 -p 50070 -i -t sequenceiq/hadoop-docker:2.5.0 /etc/bootstrap.sh –bash
use docker ps command, you get
docker set port 50070 to port 49154
you can use http://127.0.0.1:49154 to Browse HDFS.
the number 49154 is random generate.
docker run -d -p 50010:50010 -p 50070:50070 -i -t sequenceiq/hadoop-docker:2.5.0 /etc/bootstrap.sh –bash
use the up command, docker will set image’s 50070 to your machine’s 50070
docker run -d -p 9000:9000 -p 50020:50020 -p 50090:50090 -p 50070:50070 -p 50010:50010 -p 50075:50075 -p 8031:8031 -p 8032:8032 -p 8033:8033 -p 8040:8040 -p 8042:8042 -p 49707:49707 -p 8088:8088 -p 8030:8030 -i -t sequenceiq/hadoop-docker:2.5.0 /etc/bootstrap.sh –bash
