cd $HADOOP_PREFIX
bash: cd: /root/hadoop-2.10.1: No such file or directory

I wonder about the meaning of “$HADOOP_PREFIX” and whether should I installation as root or not.

Hi,

Thanks for the comment.

The error is because the user is not having permission to upload files using WebUI(HTTP).

You have to set the user in core-site.xml.

hadoop.http.staticuser.user

You can use hdfs dfs command to import/export files into hdfs.

$ hdfs dfs -put

Thanks
MohanSivam

How to evaluate

Folder Info:
Permission Owner Group Size Last Modified Replication Block Size Name
-rwxrwxrwx root supergroup 133 B Dec 18 15:10
