Error using HDFS connector with secure cluster CCDH

ranya

Hello to all,

when using HDFS connector i have this error: "USER"is not allowed to impersonate admin

HTTP code: 500, type: org.apache.hadoop.ipc.RemoteException

I have configured my DSS instance using this cmd: I didn't used the dss keytab to configure but another user who have access to my CDH cluster

./bin/dssadmin install-hadoop-integration -keytab ABSOLUTE_PATH_TO_KEYTAB_FILE -principal KERBEROS_PRINCIPAL

I have UIF configured

THank you for your response

Hi,

This is likely due to the incomplete configuration of the impersonation on the CDH cluster. Please see :

https://doc.dataiku.com/dss/latest/user-isolation/reference-architectures/cloudera.html#configure-your-cloudera-cluster for the steps required.

This error will usually occur if :

a) "hadoop.proxyuser.hive.groups" does not contain dssuser ( the UNIX user which runs the DSS software)

b) "hadoop.proxyuser.hive.hosts" does not contain the DSS host.

c) A restart of the stale CDH components was not performed.

Can you please check these and let us know if the this does not resolve your issue.
