@Love_Cat Can you share the steps before you invoke Ambari? Did you install the agent and edit the below portion of the ambari-agent.ini? [server]
hostname=<Current_Ambari_host>
url_port=8440
secured_url_port=8441
connect_retry_delay=10
max_reconnect_retry_delay=30 And restarted the agent thereafter this should show in the ambari UI in the Add host Wizard assuming you generated and copied the SSH Private key with the correct permissions Please share your steps so we could help you resolve

@George-Megre The Master nodes firstly are not meant for launching tasks or interaction. Edge or gateway nodes are used to run client applications and cluster administration tools. Setup of Edge/gateway node is similar to any Hadoop node except no Hadoop cluster services runs on the GW/Edge nodes they are mere entry points and connection gateway to the Master Components like HDFS (NN) HBASE etc provide you have installed the client libraries. In your case, I am sure you have the Hbase client/gateway roles on the 3 nodes and not on the master noded. The HBase client role gives the connectivity to Hbase but again I don't see why you would like to connect /initiate the HBase shell from the master node? Geoffrey

@TonyQiu Sorry been away for a while. Creating a table in a kerberized cluster should be possible as hbase. I just tried it out see the flow below.. I didn't need to specifically kinit as the user hbase had a valid Kerberos ticket Switch to hbase user [root@malindi keytabs]# su - hbase
Last login: Wed May 25 21:51:56 CEST 2022 Check if kerberos ticket is valid [hbase@malindi ~]$ klist
Ticket cache: FILE:/tmp/krb5cc_1016
Default principal: hbase-jair@KENYA.KE
Valid starting Expires Service principal
05/25/2022 21:51:57 05/26/2022 21:51:57 krbtgt/KENYA.KE@KENYA.KE Connect to hbase shell as hbase [hbase@malindi ~]$ hbase-shell List existing tables hbase(main):006:0> list

@iamfromsky The path you are mentioning has permissions issues. As the root user can you # chmod 777 /run/cloudera-scm-agent/process/9392-yarn-NODEMANAGER/creds.localjceks Then retry if that's successful then fine-tune the permissions . Hope that helps
