@ARUNKUMAR RAMASAMY - Ranger UI will show audit data from either Solr or DB. Since DB support will be deprecated from future releases, you are recommended to move to Solr. Audit to HDFS is for long term storage and this can be done in addition to Solr.

Restarting is the only way

@Anna Shaverdian Can you please share your blueprint? Ranger Admin's DB password settings should go in "admin-properties" section.

@Anna Shaverdian DB pre-requisites need to be met before creating the cluster through the blueprint.

Yes, if the users are removed from Ranger DB, service users also need to be re-sync'ed.

1] Did the DB also get cleaned up? Otherwise, I don't see why repo is not there. 2] If ranger service is deleted, plugin should have been disabled also, so that it does not try to communicate to ranger. 3] After ranger is added again, if using the same DB, repo should be there. If using diff. DB, it should get created when hive plugin is enabled again and hive is restarted

@Anna Shaverdian 1] For this, existing keys need to be imported into Ranger KMS (using a script provided by Ranger KMS) 2] Please check your KMS repo configuration. Looks like you are using kerberos, but the repo config user name is not a valid kerberos user. Please refer the docs here. http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.4/bk_Ranger_KMS_Admin_Guide/content/ch02s01s03.html Since KMS repo is already created, username needs to be changed directly in the ranger UI, not in Ambari.

Please see my suggestion at https://community.hortonworks.com/questions/14329/hiveserver2-wont-start-after-changing-rangers-admi.html

@Adi Jabkowsky There are two users involved - admin (advanced ranger-env) and amb_ranger_admin (admin settings). Can you verify both users password are correct in ranger and ambari UI?
