即集群外主机访问Hadoop(2)

[hadoop@localhost ~]$ hdfs dfs -ls
Found 1 items
drwxr-xr-x  - hadoop supergroup          0 2018-02-22 23:41 output
[hadoop@localhost ~]$ vi my-local.txt
hello boy!
yehyeh

上传本地文件至集群

[hadoop@localhost ~]$ hdfs dfs -mkdir upload
[hadoop@localhost ~]$ hdfs dfs -ls upload
[hadoop@localhost ~]$ hdfs dfs -ls
Found 2 items
drwxr-xr-x  - hadoop supergroup          0 2018-02-22 23:41 output
drwxr-xr-x  - hadoop supergroup          0 2018-02-23 22:38 upload

ps:注意本地java版本与master拷贝过来的文件中/etc/hadoop-env.sh配置的JAVA_HOME是否要保持一致没有验证过，本文是保持一致的。
