+Jing Hi Philippe,
When setting dfs.hdfs.policy to HTTPS_ONLY, you typically have to enable SSL on your cluster. http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.0/bk_hdfs_admin_tools/content/configuring_datanode_sasl.html This question is better suited for the HDFS team.

In advance, tank you for your feedback
