Affects Version/s: 2.6.0
Fix Version/s: None
Ambari 2.6.0 with HDP 2.6.3
In Ambari UI, there is no dfs.permissions.superusergroup property, although it should be presented in HDFS > Advanced hdfs-site section.
When trying to add this property using Custom hdfs-site, error stating the property already exists is presented to user.
May have connection to https://issues.apache.org/jira/browse/AMBARI-22086
Steps to reproduce:
- Install HDP 2.6.3 using Ambari 2.6.0 as described for example in this doc: https://docs.hortonworks.com/HDPDocuments/Ambari-220.127.116.11/bk_ambari-installation/content/ch_Getting_Ready.html
- Try to set dfs.permissions.superusergroup on service HDFS under Configs > Advanced, should go into Advanced hdfs-site (or Custom hdfs-site).
- result: property is not presented in UI in section Advanced hdfs-site nor it can be added to Custom hdfs-site since the Add property dialog reports the property already exists
Expected behavior: Property should be present in Advanced hdfs-site in UI.
notes: property exists in configuration on disks: /etc/hadoop/conf/hdfs-site.xml contains the key dfs.permissions.superusergroup, with default value of "hdfs".

And since in older versions it used to work, may it related to this fix: https://issues.apache.org/jira/browse/AMBARI-22086
