name : update-location-hdfs.rst **To update your transfer location with a new agent** The following ``update-location-hdfs`` example updates your DataSync HDFS location with a new agent. You only need the ``--kerberos-keytab`` and ``--kerberos-krb5-conf`` options if your HDFS cluster uses Kerberos authentication. :: aws datasync update-location-hdfs \ --location-arn arn:aws:datasync:us-west-2:123456789012:location/loc-abcdef01234567890 \ --agent-arns arn:aws:datasync:us-west-2:123456789012:agent/agent-1234567890abcdef0 \ --kerberos-keytab file://hdfs.keytab --kerberos-krb5-conf file://krb5.conf Contents of ``hdfs.keytab``:: N/A.
