Any body can help.
my hdfs-site.xml has the following in HA NN and DN

My hue.ini has

Oh Ok, Thank you Sandy. I'm actually running the Hue instance in EMR cluster, so I think I can't apply any changes here with cloudera packages.
Cloudera support team, if you have a possible solution for this please leave your comments. I could see this issue was raised by several developers but there were no apt solutions on this.

We need to know exactly what action you are taking and what happens when you take it. While your issue may be the same or similar to what was described earlier in this thread, we can't tell till we see your info.
Please also review your Hue log (/var/log/hue/runcpserver.log by default) at the time the problem occurs and share any log messages/exceptions you see at that time. This should provide some background to start looking at the issue.

I get this error on initial signon within HUE web UI.
Cannot access: /. Note: you are a Hue admin but not a HDFS superuser, "hdfs" or part of HDFS supergroup, "supergroup".
It should be taking me to my home directory "/user/lar00181" but instead is taking me to "/" root. The error is correct in that I do not have rights to access /. What I cannot figure out is why it is taking me to root in the first place.

In the Cloudera Manager, make sure that you have started HDFS and all the necessary services. I ran into this problem as well, but starting the command cluster solved the issue.

Hue superusers are different from hdfs superusers. With this error message, it complains that the admin and hdfs users you created through hue are not part to hdfs superuser. You should be able to fix the issue by fixing the permission of the directories to the user/group on the cluster.
Hope this helps!
