Shouldn't this be done by Hive / Slider themselves before starting the LLAP application ? I have not read anything about this in the documentation. </P><P>My goal was to show that anonymous connections are allowed (read) but not for writing, so I cannot explain this exception :</P><PRE>2017-12-05 12:05:48,058 [main] WARN client.SliderClient - Error deleting registry entry /users/hive/services/org-apache-slider/llap0: org.apache.hadoop.registry.client.exceptions.NoPathPermissionsException: `/registry/users/hive/services/org-apache-slider/llap0': Not authorized to access path; ACLs: [null ACL]: KeeperErrorCode = NoAuth for /registry/users/hive/services/org-apache-slider/llap0 </PRE><P> Why does Slider run without Kerberos credentials ?</P><PRE>2017-12-05 12:05:47,992 [main] INFO zk.RegistrySecurity - Enabling ZK sasl client: jaasClientEntry = Client, principal = null, keytab = null</PRE><P> Just to remember : the original problem is that LLAP does not start. </P><P>I'll post the YARN log later</P><P>Cheers </P> Fri, 08 Dec 2017 20:52:29 GMT mpaul 2017-12-08T20:52:29Z
