Usually a product is not supported until Cloudera finds it stable and production ready. Therefore we encourage you to evaluate CDP [2].</P><P>&nbsp;</P><P data-unlink="true">The "KerberosName$NoMatchingRule: No rules applied to mzeoli@COMPANY.PRI" exception usually&nbsp;occurs when the&nbsp;<SPAN>hadoop.security.auth_to_local rules does not provide a mapping to the local linux user (the user has to exist on the node that is extracted from the kerberos principal). Also make sure that the krb5.conf is readable by the user.</SPAN></P><P data-unlink="true">&nbsp;</P><P data-unlink="true"><SPAN>Please let us know if this information was helpful!</SPAN></P><P data-unlink="true">&nbsp;</P><P data-unlink="true"><SPAN>Kind regards:</SPAN></P><P data-unlink="true"><SPAN>Ferenc</SPAN></P><P data-unlink="true">&nbsp;</P><P data-unlink="true"><SPAN>[1]&nbsp;<A href="https://docs.cloudera.com/runtime/7.1.0/running-spark-applications/topics/spark-submitting-applications-using-livy.html" target="_blank">https://docs.cloudera.com/runtime/7.1.0/running-spark-applications/topics/spark-submitting-applications-using-livy.html</A></SPAN></P><P data-unlink="true"><SPAN>[2]&nbsp;<A href="https://docs.cloudera.com/cdpdc/7.0/installation/topics/cdpdc-trial-download-information.html" target="_blank">https://docs.cloudera.com/cdpdc/7.0/installation/topics/cdpdc-trial-download-information.html</A></SPAN></P> Wed, 27 May 2020 13:58:46 GMT Bender 2020-05-27T13:58:46Z
