@Mondi    You can simply add the hue admin user to the group of sentry admin. Both the group and user should exist locally on cluster nodes and the hue admin user should be a part of this sentry admin group. Refer below document to set ACLs for the directories. https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cdh_sg_hdfs_ext_acls.html#xd_583c10bfdbd326ba--6eed2fb8-14349d04bee--76a9   Hope this helps, Paras Was your question answered?

@Mondi    The unable to obtain groups message indicates that the admin user on hue is not added to the cluster nodes. The user and its associated access groups should also be present on the cluster nodes. Please create the user if it does not exist, add it to the group of sentry admins and retry.   What is the CDH version of your cluster? Are you able to modify ACLs of the HDFS directories from the command line using setfacl commands as the same user? ... View more

@Mondi  You cannot disable the download option in Hue per user. A more plausible way to not allow any specific path download would be to simply deny the user permission to read or write to the HDFS directory itself. ... View more

@Amey3    You cannot directly unzip the files in HDFS. You would have to uncompress the files on local and then place it on HDFS.   You can use Hue which uses a shell action in oozie to automate this. The files are uncompressed in the local and then uploaded to HDFS. https://gethue.com/extract-archives-as-oozie-job/   Hope this helps, Paras Was your question answered?

@Mondi    It is highly recommended to install kerberos as a prerequisite before using sentry. HiveServer2 and the Hive Metastore (HMS) running with strong authentication. For HiveServer2, strong authentication is either Kerberos or LDAP. For the Hive Metastore, only Kerberos is considered strong authentication (to override, see Securing the Hive Metastore). Below document mentions the prerequisites in detail: https://docs.cloudera.com/documentation/enterprise/latest/topics/sg_sentry_before_you_install.html#prerequisites   Hope this helps, Paras Was your question answered?

@Mondi    The property setting the retainment period can be found at: Cloudera Manager -> Cloudera Management Service -> Configuration -> and in the search field please type: "Navigator Audit Server Data Expiration Period" After reducing this retention period and restarting the Nav Audit server role, the tables/data should be purged.  If you still see old audit data remaining you can proceed with manual purging: Connect to your database. > show databases; > use <nav_audit_database>; > show tables; > drop table <audit_event_table>; You can also set audit filters for difffernt services to have a control on audit collection. https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cn_admcfg_audit_filters.html   Hope this helps, Paras Was your question answered?
