This is WRT Ambari2.1.1 in the cluster where Ranger is enabled.
Steps to reproduce-
1- Go to Advanced configs tab for HDFS
2- uncheck "Enable Ranger for HDFS" in "Advanced ranger-HDFS-plugin-properties"
3- The pop up shows up that the property "dfs.permissions.enabled" for HDFS service will be modified to "false"
This is wrong. These properties should not be modified.
