I've been trying to launch Hadoop by typing any command, for example, entering " Hadoop fs -ls" in the terminal and I get this error WARN ipc.Client: Failed to connect to server: quickstart.cloudera/XXX.XXX.XX.128:8020: try once and fail.

ls: No Route to Host from quickstart.cloudera/XXX.XXX.XX.128 to quickstart.cloudera:8020 failed on socket timeout exception: java.net.NoRouteToHostException: No route to host; For more details see: http://wiki.apache.org/hadoop/NoRouteToHost Notice Hadoop was running perfectly after my IP suddenly changed to XXX.XXX.XX.129. this error accrued. I don't know how to make/configure Hadoop launch on the same IP address Thank you

My problem is that I've been following a lot of documents that can help me with installing, and after finishing all the steps,I've found that krb5kdc or kadmin is not running / enabling. for example when i type " service kadmin start " or " service krb5kdc start" command. its doesnt do /show me anything. i tried many other commands " systemctl start krb5kdc" or " systemctl enable krb5kdc". So does anyone knows what is the problem. PS. the last document that I've been following is this video : https://www.youtube.com/watch?v=-pBh7fgV6w4&t=434s
