Question

# #sudo -u hdfs hadoop -mkdir test
# #sudo -u hdfs hadoop fs -put /root/hadoop-2.0.4-alpha/share/hadoop/mapreduce/word.txt    test
put: `/root/hadoop-2.0.4-alpha/share/hadoop/mapreduce/word.txt': No such file or directory

I am sure the file word.txt is there!  

And I browse hdfs from CM web UI http://xxx.xx.xx.xx:7180/cmf/services/25/hdfs/browse  
got Reports Manager () the connection is unavailable or unresponsive.
What is the problem? can any one help? pleases! Thanks in advance!

我跑：

#sudo -u hdfs hadoop fs -ls -R /

Answer 1

您的hdfs用户是否有权阅读

/root/hadoop-2.0.4-alpha/share/hadoop/mapreduce/word.txt

转到

/root/hadoop-2.0.4-alpha/share/hadoop/mapreduce /

待办事项

ls -l </ p>

检查word.txt的权限是什么

将其设为777然后再试一次

CM安装CDH4（hadoop2.0），不要把文件放到fdfs中
