Why does “hadoop fs -mkdir” fail with Permission Denied?

Question

I am using Cloudera on a VM machine that I am playing around with. Unfortunately I am having issues copying data to the HDFS, I am getting the following:

Answer 1

I resolved the issue by creating a supergroup in /etc/group and updated the user logins on it. I mean user should be part of HDFS supergroup to have access to write on HDFS.

$vi /etc/group

supergroup:x:30000:root

Later was able to write on HDFS. Hope it helps
