About Kerberos on the Hadoop Cluster

If your enterprise uses Kerberos security, you must have all valid tickets in place on the cluster. When SAS In-Database Technologies for Hadoop is deployed, the HDFS user must have a valid ticket.
Note:
  • For all Hadoop distributions except MapR, the default HDFS user is hdfs. For MapR distributions, the default HDFS user is mapr.
  • If you set a maximum lifetime for Kerberos tickets, ensure that the person deploying SAS In-Database Technologies for Hadoop is aware of the expiration date of the ticket.
After configuring Kerberos, provide the necessary configuration values to the vApp user. See Providing vApp User Configuration Information.
Note: SAS Data Loader for Hadoop does not provide Kerberos validation. All configuration values must be entered correctly in the SAS Data Loader for Hadoop vApp or errors result during its operation.
