hadoop user file permissions

Question

i have a problem in setting hadoop file permissions in hortonworks and cloudera.

My requirement is:

1. create a new user with new group  
2. crea         


        

Answer 1

I believe you set the wrong property to enable permissions. You need to set the following property in hdfs-site:

dfs.permissions.enabled = true

This is a good resource for HDFS permissions

Answer 2

You should repeat your step on the master node (active namenode).

After that, run

hdfs dfsadmin -refreshUserToGroupsMappings
