Setting Properties That Depend on Service Usernames/Groups
Some properties must be set to match specific service user names or service groups. If you have set up non-default, customized service user names for the HDFS or HBase service or the Hadoop group name, you must edit the following properties, using Services > Service.Name > Configs > Advanced:
HDFS Settings: Advanced
- dfs.permissions.superusergroup
The same as the HDFS username. The default is "hdfs"
- dfs.cluster.administrators
A single space followed by the HDFS username.
- dfs.block.local-path-access.user
The HBase username. The default is "hbase".
MapReduce Settings: Advanced
- mapreduce.cluster.administrators
A single space followed by the Hadoop group name.
