@Shraddha Singh You are trying to run the dfsadmin command when the Namenode is not yet started. Please ensure the namendoe is in started status in Ambari

@christophe VALMIR Usually, after the restart give the process a minute or 2 for the processes to pick up. Please don't forget to vote a helpful answer as the issue is resolved,that way other HCC users can quickly find the solution when they encounter the same issue. HTH

@Sampath Kumar Ask your AD admin The above should match the krb5.conf

Shelton · ‎02-09-2019

@Sampath Kumar I think there is a mismatch in the encryption types in your krb5.conf and the AD. Have a look at the below document and align your config. Windows Configurations for Kerberos Supported Encryption Types HTH

@ Michael Bronson Kafka requires the machine's hostname to be resolvable to connect back to itself. If you look under the config files and open up the server.properties you will see this line but most appropriate have localhost because in the event that the IP changes Kafka will still work seamlessly advertised.host.name=localhost or xx.xx.xx.xxx Make sure this IP matches your current IP, you can check for your IP here.

@Howchoy Nice to know it worked but the real issue is that the tookit.sh interprets the $ sign as a special character that's the reason you MUST use an escape character for it to work and the length of more than 13 characters. I am sure if you tried "Ce\$18C" it won't work either.
