docker 配置hadoop问题

1.root@caf2f69691f3:/opt/hadoop-2.6.0/sbin# hdfs dfsadmin -report

Configured Capacity: 0 (0 B)

Present Capacity: 0 (0 B)

DFS Remaining: 0 (0 B)

DFS Used: 0 (0 B)

DFS Used%: NaN%

Under replicated blocks: 0

Blocks with corrupt replicas: 0

Missing blocks: 0

namenode没有开启 执行 /opt/hadoop-2.6.0/sbin/hadoop-daemon.sh start datanode

2.网页访问docker容器的hadoop 把本地端口50071绑定容器端口50070 （hadoop hdfs默认访问端口）

sudo docker run -it -p 50071:50070 --name master1 shanyx/ubuntu:hadoop /bin/bash

3.sudo docker ps --no-trunc查看容器完整id

把本地文件传入已开启docker容器 sudo cp ins/a /var/lib/docker/devicemapper/mnt/caf2f69691f3f05dfa7e3da82763cfd2a0c5ea718a082da99adaa758eeee8cb4/opt/
