I do not believe there is any purging of the Cloudera Manager audits.  I checked and did not see any code that performed a purge or deletion.  Let us know if you see anything that suggests otherwise.   Thanks,   Ben ... View more

Hi... this is old, but just came across it.   hiveserver2_enable_impersonation is set at the HiveServer2 role level, so you would need to use the full path to your HiveServer2 role.  for instance:   curl -X PUT -H "Content-Type:application/json" -u admin:admin -k "https://localhost:7183/api/v12/clusters/cluster/services/hive/roles/hive-HIVESERVER2-609b6bea2fc852513192152e64d3ec19/config" -d '{ "items" : [ { "name" : "hiveserver2_enable_impersonation", "value" : "false" } ] }'   Since the attribute does not exist at the service level (where you attempted to set it), the attribute is not found.   I hope that might help you or others.   Cheers,   Ben ...
