@Geoffrey Shelton Okot thanks for you reply. I have used the same database for reinstalling the Ranger. I was assuming that Ranger will delete all of its tables during the uninstallation

Dear experts, Due to some problem, we have reinstalled the Ranger and KMS services. However , if i open the ranger UI , it is still showing the old policies and even the ranger admin passwords are not getting changed. Kindly help on what might be the issue.

Dear experts, We are enabling kerberos in our cluster with integrating it to Active Directory. The Kerberos has been enabled however during the service restarts, all the services are being failed with the below error, could you please assist on this ? /usr/bin/kinit -kt /etc/security/keytabs/smokeuser.headless.keytab ambari-qa-hdp@HADOOP.LOCAL;' returned 1. kinit: Preauthentication failed while getting initial credentials Zookeeper logs: 2018-06-17 14:02:52,217 - INFO [PurgeTask:DatadirCleanupManager$PurgeTask@138] - Purge task started. 2018-06-17 14:02:52,218 - INFO [main:QuorumPeerMain@127] - Starting quorum peer 2018-06-17 14:02:52,229 - INFO [PurgeTask:DatadirCleanupManager$PurgeTask@144] - Purge task completed. 2018-06-17 14:02:52,814 - ERROR [main:QuorumPeerMain@89] - Unexpected exception, exiting abnormally java.io.IOException: Could not configure server because SASL configuration did not allow the ZooKeeper server to authenticate itself properly: javax.security.auth.login.LoginException: Pre-authentication information was invalid (24) at org.apache.zookeeper.server.ServerCnxnFactory.configureSaslLogin(ServerCnxnFactory.java:207) at org.apache.zookeeper.server.NIOServerCnxnFactory.configure(NIOServerCnxnFactory.java:87) at org.apache.zookeeper.server.quorum.QuorumPeerMain.runFromConfig(QuorumPeerMain.java:130) at org.apache.zookeeper.server.quorum.QuorumPeerMain.initializeAndRun(QuorumPeerMain.java:111) at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:78) Because of this issues, it is not allowing us to disable the kerberos now.

@Jay SenSharma Thanks for helping out. Restarting the shellinabox service in the sandbox helped me to access the webssh.

chiru_tnk · ‎10-18-2017

@Jay SenSharma Command "ssh root@127.0.0.1-p 2222" worked for me to use hadoop commands. However, i am still not able to access web ssh client, please find the details below once i logged into the docker container. [root@sandbox ~]# service shellinaboxd status shellinaboxd (pid 2717) is running...
