Hello @pauljoshiva You need to add the new nodes with a new config group. One set of DNs in default config group (where the storage directories are laid from /hdp/hdfs01 - /hdp/hdfs09) and anotehr set of DNs in new config group (with directories /hdp/hdfs01, /hdp/hdfs02, /hdp/hdfs03). That way you can have all DNs added to cluster with 2 separate config groups.

Hello @ryu The command that you are using is incorrect or maybe a typo. There is a 's' missing after log in the command. Use below command to fetch the logs. Yarn logs -applicationId <application id of the job> Please accept this answer if you find it useful to resolve your issue. Regards, Amir Mirza

I made a haste before getting the result just by concluding over the portal. Contact certification@cloudera.com for any queries related to Certifications. I cleared the exam and I received my certificate and badge.

Hi @Magudeswaran Ambari server uses appropriate database base connector which is located under /user/share/java/*<databasename>.jar This same connector jar is used to connect to any external or internal database. It needs to be mentioned using ambari-server --jdbc * command. Refer documentation for exact command. Issue could be due to the connector jar that is configured for ambari to use. For eg. Ambari is configured to use postgres but you are trying to connect to Mariadb and since it doesn't has the proper jar configured, it won't connect and you will face issue. Let me know if this resolves your issue. Else please share the screen shot and error logs to check further.

Hi @Aco Yes, you can create it manually. Check the zookeeper document on how to create those directories. It happens due to insufficient permissions. You need to create the directories from zookeeper cli and set appropriate permission, rest of the data and file creation will be taken care by zookeeper. I will see if I could find the exact steps to share it with you

Hi @Koffi Can you share gateway.log and audit.log during the timeframe when you are accessing namenode ui. If namenode ui was accessible earlier, can you check if there was a failover done during the time from when it is not accessible. Please share advanced topology file to check your configuration.

Try to increase the heap size for nodemanager from Yarn -> Configs and see if that resolves your issue. If not then probably you will have to do a performance or query tuning. Please accept this answer if it helps you resolve your issue.
