Hi @Ani1991 , Suspecting Kerberos related parameters are incorrectly configured in the Kafka service repo in Ranger. Can you please try the below solution :     -- Ranager Admin UI > edit kafka service repo cm_kafka > Add configs in "Add New Configurations" -- Add below configs. (Change the config accordingly) for protocol   bootstrap.servers <kafkaBroker>:Port security.protocol SASL_PLAINTEXT sasl.mechanism GSSAPI kafka.keytab <keytab> kafka.principal <prinicipal>   This config needs a kafka keytab  path , copy kafka keytab to ranger admin host with ranger:ranger permissions set. ...

Hi Justin, Do we have anything in the CM server logs apart from this ? Try to restart the CM server and see how it goes. If it is a new cluster then probably check the Java version is compatible or not. The below link will be able to show Java compatible details for CDP and HDP :   https://supportmatrix.cloudera.com/#Hortonworks ... View more

Hi, What is understood is you are trying to add a new agent host. And while doing so you are getting connection refused. If you are trying to install the agent manually , then check if the agent RPM version is same as of Ambari server using command : rpm -qa | grep -i ambari.  Check if the connecting port between agent and server is open and is not blocked.  Check the agent.ini file has the correct ambari server hostname.  ...

Hi Soheer, From the logs it seems the gateway SSL cert got expired.   Can you please locate the gateway.jks file in the Knox host , by default it is in location :  /var/lib/knox/data*/security/keystores/gateway.jks   Move the gateway.jks file to any backup location or rename it. Then restart the Knox service , while restart it will create the new gateway,jks and the service should start up. ... View more
