The cluster uses an OAUTH token for authentication for the impersonation user, the Hadoop staging user, and any other user who runs jobs on the cluster from the Data Integration Service.
Log in to Ambari Web UI with the Azure Active Directory user credentials to generate the OAUTH token for authentication for the Informatica users. For definitions of these users, see
Verify and Create Users.
The HDInsight cluster requires an OAUTH token only if the mapping accesses ADLS Gen1 resources.
