2. 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
Property Name | Value |
|---|---|
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
Property Name | Value |
|---|---|
mapreduce.cluster.administrators | A single space followed by the Hadoop group name. |
