First, I setup cluster with 7 hosts. Then I added another 2 hosts which are new installed OS. All done by Ambari UI.
Currently, the 9 hosts runs no problem.
But I noticed the UID and GID on later 2 hosts are some different with the original 7 hosts.
such as:
The original 7 hosts:
zookeeper:x:1000:1000::/home/zookeeper:/bin/bash
