@Punit kumar Please run the following command to verify the permissions on HDFS directory "/"

# su - hdfs
# hdfs dfs -stat "%u %g" /
hdfs hdfs

It should be owned by "hdfs:hdfs" if it is not then you can fix it by running the following command:

# hdfs dfs -chwon hdfs:hdfs /

- It is Hue code that is explicitly checking for the default permission :

And the default superuser is defined in "hue.ini" as following:

default_hdfs_superuser=hdfs
