Enable an NTP Service

Runtime requires that you configure a Network Time Protocol (NTP) service on each machine in your cluster. Most operating systems include the ntpd service for time synchronization.

Some operating systems use chronyd by default instead of ntpd. If chronyd is running (on any OS), Cloudera Manager uses it to determine whether the host clock is synchronized. Otherwise, Cloudera Manager uses ntpd.

Please refer your OS vendor's documentation to install and configure either ntpd or chronyd.
