    Hi @saurabh
    ,

    Regarding the "superuser cannot impersonate User pocuser" error, please make sure that the hadoop.proxyuser.dataiku.groups and hadoop.proxyuser.dataiku.hosts configurations are added to the core-site.xml file: https://doc.dataiku.com/dss/latest/user-isolation/reference-architectures/hdp.html#configure-your-cluster

    You will need to add the additional connection parameter below to your Hiveserver2 connection URL in order to tell Hiverserver to impersonate DSS users.

    ;hive.server2.proxy.user=${hadoopUser}
    Note that the ${hadoopUser} will be automatically be replaced by the current user for each connection.

    As far as the "ProxyUser "superuser" configuration not found" error, I would suggest to troubleshoot further with your Hadoop Admins and double check your Hadoop cluster settings as the next step.

    Thanks,

    Jordan
