I did hive integration with Ranger and PAM authentication which is working correct on single machine environment. Can somebody explain what is the difference between PAM - sshd & passwd? which one we should use in multiple machine HDP environment. Where Ranger Usersync and Hive server2 is on two different hosts. Thanks in Advance ... View more

We have integrated Hive and Ranger (HDP 3.1) and we are able to login using beeline. We have created Username and password using Ranger's user creation page. But beeline only validate with username not with password. It accepts any password with same user and we got access with tables or schema. 1). If we provide wrong username then it says access denied 2). if we provide correct username and wrong password then it can login and access data which is wrong and should say access denied. Thanks in Advance. ... View more

HI All, I am working to integrate ranger and presto and following this URL but ended with error and integration is not successful. Steps: Created a ranger-${RANGER_VERSION}-presto-plugin.tar.gz file. Extracted tar file to ranger-presto-plugin Changed install.properies file. Run ./enable-presto-plugin.sh It was successful run but It did not create access-control.properties & rules.json file. And I created these files manually in /etc/presto. Now presto is not starting and failed with the below error. 2019-06-21T04:59:21.731Z ERROR main com.facebook.presto.server.PrestoServer Access control ranger is not registered java.lang.IllegalStateException: Access control ranger is not registered at com.google.common.base.Preconditions.checkState(Preconditions.java:585) at com.facebook.presto.security.AccessControlManager.setSystemAccessControl(AccessControlManager.java:136) at com.facebook.presto.security.AccessControlManager.loadSystemAccessControl(AccessControlManager.java:118) at com.facebook.presto.server.PrestoServer.run(PrestoServer.java:142) at com.facebook.presto.server.PrestoServer.main(PrestoServer.java:73) Do we need to use ranger-servicedef-presto.json anywhere because its not mentioned in ranger presto integration URL. OR any another link which I can follow which is having all information. Thanks Bharat Bhushan ... View more

Hi All, I am working on Ranger Kylin plugin installation. And I have completed the plugin installation. Ranger is showing Kylin services and policy on its web page. Ranger admin UI is successfully connected with kylin and policy cache json file in etc/ranger is also created. I have also updated kylin.properties file with "kylin.server.external-acl-provider". Now, when I create a new user using ranger admin UI and give permission to this user on kylin policy. After that using the same user I am not able login in Kylin GUI. I have checked logs and it says User not found. Only spring security code is in exception, No ranger code stack trace is available in exception. I guess, Kylin is not switched to ranger auth. Do I need to add more properties in kylin.properties to switch on Ranger policy? So, Kylin can authenticate using ranger users? Thanks ... View more

Hi All, I have a already setup HDP 3.0 cluster having total 7 machines with 3 worker nodes. I also installed Ranger to do security and a user already created on hive. Now I want to access hive table using spark. I have tried both using spark-shell and java code But both is getting same error. I am using spark llap to provide username/password for hive. But spark got an Exception:"No service instances found in registry" Log scala> df.show [Stage 0:> (0 + 0) / 1]18/12/10 17:08:51 WARN TaskSetManager: Stage 0 contains a task of very large size (423 KB).
