Network Time Protocol
The clocks on all nodes in your cluster and on the machine running the browser through which you access the Ambari web interface must be able to synchronize with each other.
To install the NTP service and ensure that it is started at startup, run the following commands on each host:
- RHEL/CentOS 7
- RHEL/CentOS/RockyLinux 8
- Ubuntu 22.04
sudo yum install -y ntp
sudo systemctl enable ntpd
sudo dnf install -y ntp
sudo systemctl enable ntpd
sudo apt-get install -y ntp
sudo update-rc.d ntp defaults
