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

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.
