PowerScale OneFS HDFS Configuration Guide

Creating a local Hadoop user

OneFS must be able to look up local Hadoop users by name. If there are no directory services in an access zone that can perform a user lookup, you must create a local Hadoop user that maps to a user on a Hadoop compute client for that access zone. If directory services are available, a local user account is not required. You can create a local Hadoop user using either the OneFS web administration interface (Web UI) or the command-line interface (CLI).
