Enabling Kerberos authentication for Spark
To authenticate against a Kerberos-enabled cluster, the Kerberos configuration needs to be verified first. The configuration can be found in krb5.conf file, which includes the locations of KDCs and admin servers of Kerberos's realms of interest, defaults for the current realm and Kerberos applications, and mappings of the host names onto Kerberos's realms.
