Hello everyone, I am trying to integrate Datahub (v0.8.44) with Apache Ranger (2.2.0). I have managed to connect Datahub to Ranger, although I am getting some errors that I don't know why they are occuring (although I think the errors obtained from Ranger are the source of the errors obtained in Ranger). Errors obtained in the GMS container:

WARN  o.a.r.a.client.RangerAdminRESTClient:1228 - Received 404 error code with body:[null], Ignoring
WARN  o.a.r.a.client.RangerAdminRESTClient:868 - Error getting policies. secureMode=false, user=datahub (auth:SIMPLE), response={"httpStatusCode":400,"statusCode":0}, serviceName=ranger_datahub
WARN  o.a.r.plugin.util.PolicyRefresher:393 - cache file does not exist or not readable '/tmp/datahub_ranger_datahub.json'
ERROR o.a.r.a.client.RangerAdminRESTClient:1220 - Error getting Roles; service not found. secureMode=false, user=datahub (auth:SIMPLE), response=404, serviceName=ranger_datahub, lastKnownRoleVersion=-1, lastActivationTimeInMillis=1663933107990

Errors obtained in Ranger trying to create the service named "ranger_datahub":

Error! Datahub failed to find service class com.datahub.authorizer.plugin.ranger.DataHubRangerAuthPlugin. Resource lookup will not be available. Please make sure plugin jar is in the correct place.

I don't know why I am obtaining the latter error as I have downloaded the datahub plugin in the route

/opt/ranger-2.2.0-admin/ews/webapp/WEB-INF/claases/ranger-plugins/datahub

and execute the curl command to define the service inside of Ranger. Any help would be appreciated.

have you solved，i have the same problem.thanks.

No, because the ranger integration has some prerquisites, being the following the most problematic of them:

Basic authentication is enabled on Apache Ranger Service

as my Ranger has Kerberos Authentication.
