Kerberos

This section describes how to set up Kerberos under CES HDFS.

Note:

MIT Kerberos and Red Hat IPA Kerberos are supported.
As per the prerequisites of Kerberos, the hostname of the cluster nodes that belong to the cluster must be in lowercase.
If you need to set up more than one HDFS Transparency cluster by using a common KDC server, see If Kerberos was configured on multiple HDFS Transparency clusters using a common KDC server and the supplied gpfs_kerberos_configuration.py script, kinit with the hdfs user principal fails for all the clusters except the most recent one.
This limitation has been fixed in HDFS Transparency 3.1.1.6.
