Hello, you are right indeed! I put the internal hostname in each node and the error disappears 127.0.0.1 localhost.localdomain localhost
172.31.16.164 master.sysdatadigital.it master
172.31.19.139 slave1.sysdatadigital.it slave1
172.31.25.187 slave2.sysdatadigital.it slave2
172.31.28.223 slave3.sysdatadigital.it slave3
172.31.16.104 slave4.sysdatadigital.it slave4 Many thanks, M

@m4x1m1li4n To validate the zookeeper ports can you run the snippets and share the output, it seems CDH uses the port 4181 for its zookeeper I am from the HDP world! Using port 2181 echo "stat" | nc server.example.org 2181 | grep Mode $ telnet slave3.sysdatadigital.it 2181 Using port 4181 echo "stat" | nc slave3.sysdatadigital.it 4181 | grep Mode $ telnet slave3.sysdatadigital.it 4181 Disable the firewall in the VPC which is a subnet doesn't disable the firewall on the host please validate that all the hosts have the firewall disable Assuming you are on Centos/RHEL 7 and share the output readapt if your OS is different # systemctl status firewalld From your CM can you share the zookeeper screenshot

Hi, I have got a similar issue. My file host is the following for all hosts in my cluster: 127.0.0.1 localhost.localdomain localhost 13.48.140.49 master.sysdatadigital.it master 13.48.181.38 slave1.sysdatadigital.it slave1 13.48.185.39 slave2.sysdatadigital.it slave2 13.53.62.160 slave3.sysdatadigital.it slave3 13.48.18.0 slave4.sysdatadigital.it slave4 What did you change exactly? Many thanks, M

Hi @m4x1m1li4n ,
Looks like you used custom location. You may want to take a look at the location:
/opt/cloudera/CMCA
and see if there are some data inside. Try to move those files to different location and see if that helps.
Thanks,
Li
