@Shelton Glad that you reproduce this problem. I have ten brokers and every broker is configured with their respective IP addresses but I am afraid I cannot provide screenshot for some reasons. I have a workaround for this problem. In my own opinion, the reason of this problem is that Ambari cannot recognize IP and port bindings correctly. So to solve this is to avoiding the challenge for it. Here is my configuration now:   listeners=SASL_PLAINTEXT://0.0.0.0:9092,EXTERNAL://0.0.0.0:19092 advertised.listeners=SASL_PLAINTEXT://192.168.1.1:9092,EXTERNAL://88.88.88.88:19092 The other configurations stay unchanged. Notice that I change `listeners` so that even Ambari  cannot recognize the right IP and port binding, both ports are now available on all interfaces so there are no false alerts now. Thanks you so much for helping me on this problem and apologize for this late response. ... View more

@neha_t_jain  Great I have seen a similar question of a member asking HDP compatibility with Java 12 it's unfortunate the open sourceness of Java is gone and some companies will have to pay to use it.

@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 ...
