How to disable browsing log files in HDFS Web UI?

[#1]

Is there a way to disable browsing log files in HDFS Web UI which runs on port 50070?

Else can we completely disable the HDFS Web UI?

I don't think there is a way to disable the UI within HDFS. The only way i see is to block the port in firewall/iptables and restrict users to access the UI.
