I cannot find dfs.permissions.superusergroup via ambari (HDFS-->config) in HDP 2.6.3
When I search "dfs.permissions" I see only the parameter "dfs.permissions.enabled"
If i try to add it to the custom hdfs-site I get "Line 1: Property "dfs.permissions.superusergroup" is already defined in this configuration file"
Checking on the local file system I do see that the parameter exists but I cannot modify it via ambari.
I have cluster with HDP 2.6.1 and it is modifiable there.
OS is RHEL 7.3
Any help will be appriciated.

To me, this seems to be a bug. I tried to report it against Ambari:
Maybe it is related to this fix?

Is there a workaround for this problem, which doesn't involve upgrade/downgrade?

Here is what I got from HDP experts:
1. Edit /var/lib/ambari-server/resources/common-services/HDFS/x.x.x.x.x/configuration/hdfs-site.xml
2. Modify the XML for commenting the <property-type>GROUP</property-type> tag. Like this:
<!-- <property-type>GROUP</property-type> -->
<description>The name of the group of super-users.</description>
3. Restart Ambari

That worked, thanks! Now I can see the option on the ambari UI.

I am assuming the above change wouldn't survive future Ambari upgrade.
