Hi, Here are some details with Ranger logs (a part of it) : Usersync log : INFO PasswordValidator [Thread-64968] - Response [FAILED: [amb_ranger_admin] does not exists.] for user: amb_ranger_admin INFO PasswordValidator [Thread-64970] - Response [FAILED: [admin] does not exists.] for user: admin >>> Those are infos to say these users are not UNIX users. That's all the logs we have (hundred times a day). For me, it is not our main problem. XAPORTAL log : 2018-06-20 09:10:29,691 [http-bio-6080-exec-8] INFO org.apache.ranger.security.handler.RangerAuthenticationProvider (RangerAuthenticationProvider.java:147) - Authentication with SHA-256 failed. Now trying with MD5. 2018-06-20 09:10:29,692 [http-bio-6080-exec-8] INFO org.apache.ranger.security.listener.SpringEventListener (SpringEventListener.java:70) - Login Successful:admin | Ip Address:128.1.227.103 | sessionId=A311983F0813A5EDE4B4F34FDF558628 | Epoch=1529485829692 2018-06-20 09:10:29,698 [http-bio-6080-exec-8] INFO org.apache.ranger.biz.SessionMgr (SessionMgr.java:232) - UserSession Updated to set new Permissions to User: admin 2018-06-20 09:10:29,698 [http-bio-6080-exec-8] INFO org.apache.ranger.biz.SessionMgr (SessionMgr.java:184) - Login Success: loginId=admin, sessionId=51435, sessionId=A311983F0813A5EDE4B4F34FDF558628, requestId=128.1.227.103, epoch=1529485829698 >>> No Warning or Error CATALINA.OUT log : RemoteUnixLoginModule: RemoteUnixLoginModule::initialize() has been called with callbackhandler: org.springframework.security.authentication.jaas.AbstractJaasAuthenticationProvider$InternalCallbackHandler@12a420aa RemoteUnixLoginModule: Created RemoteUnixLoginModule >>> All good Access_log is good aswell. We don't see errors, in any Ranger log. Do you have some tips for HDFS/Ranger configuration check ? Thanks, Tom
