Hi @Muba Please check if the Hue user user1 is not part of HDFS superuser group. This might give the user access to file browser and all the hdfs directories.

You need to add the nameservice @snm1523 in most of the NN urls so that it wont go to one particular namenode. So from application side please check if any app is connecting to a particular NN mentioned hardcoded and not using nameservice

Apart from Zk ensemble, new broker details you need to have namespace updated for NN for RM nothing much will happen for Dev and Data engineer. Hive and Impala string will be changed. Tableau connection string with Hive will also change.

Hi @yagoaparecidoti , You dont have to run the balancer. The blocks will recognize the racks and it will be done automatically.

Hi @JiHoone I think all your jobs that is running is allocated only the AM resources. Do one thing first set the "Configured Max AM limit" to 20%. Then set the Minimum user limit percent to 25% and run your jobs. Set user limit factor as 0.5.

Hi @ryu , yes you can search the details in the RM logs with the application Id. You will get the details of the resources asked by the application and resources provided by the RM
