@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 :

https://github.com/cloudera/hue/blob/9916b2b6389323ad8139d709e248156a7cf943f5/desktop/libs/hadoop/sr...

.

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

default_hdfs_superuser=hdfs

https://github.com/cloudera/hue/blob/ef8812cb2033b628d90f5bffacc4ce7c27374e45/desktop/conf.dist/hue....
