介绍了一些docker的基本命令，这篇文章来安装一个HADOOP

一、下载hadoop镜像

@~/git/github/docker-ambari (master)$ docker pull sequenceiq/hadoop-docker:2.6.0Pulling repository sequenceiq/hadoop-docker7b738796aaab: Pulling dependent layers 89b52f216c6c: Download complete ... 这个一个漫长的过程Status: Downloaded newer image for sequenceiq/hadoop-docker:2.6.0

二、查看镜像

@~ $ docker imagesREPOSITORY                 TAG                 IMAGE ID            CREATED             VIRTUAL SIZEubuntu                     curl-ubuntu         aac468ce18c8        17 hours ago        204.1 MBsequenceiq/hadoop-docker   2.6.0               7b738796aaab        6 days ago          1.597 GBubuntu                     latest              9bd07e480c5b        10 days ago         192.7 MB
                          
      
                     c840fd1ab2ae        6 weeks ago         984.4 MB
      
     

三、运行hadoop

@~ $ docker run -i -t sequenceiq/hadoop-docker:2.6.0 /etc/bootstrap.sh -bashStarting sshd:                                             [  OK  ]......

四、查看结果

bash-4.1# bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar grep input output 'dfs[a-z.]+'14/12/14 09:45:31 INFO client.RMProxy: Connecting to ResourceManager at /0.0.0.0:803214/12/14 09:45:32 WARN mapreduce.JobSubmitter: No job jar file set.  User classes may not be found. See Job or Job#setJar(String).14/12/14 09:45:32 INFO input.FileInputFormat: Total input paths to process : 31

五、继续

bash-4.1# bin/hdfs dfs -cat output/*6    dfs.audit.logger4    dfs.class3    dfs.server.namenode.2    dfs.period2    dfs.audit.log.maxfilesize2    dfs.audit.log.maxbackupindex1    dfsmetrics.log1    dfsadmin1    dfs.servers1    dfs.replication1    dfs.file
