--------------------------------------

             Summary: Unable to set dfs.permissions.superusergroup using Ambari
                 Key: AMBARI-22839
                 URL: https://issues.apache.org/jira/browse/AMBARI-22839
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.6.0
         Environment: Ambari 2.6.0 with HDP 2.6.3
            Reporter: Michal Klempa


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-2.6.0.0/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".

 

This bug is also reported here: [https://community.hortonworks.com/questions/155952/how-to-modify-dfspermissionssuperusergroup-in-hdp.html]

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