ntpd or chronyd

Contributor

This page https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-installation/content/enable_ntp_o... instructs to install ntpd even if using RHEL7/CentOS7.

As far as I know, Chrony is the default in RHEL7/CentOS7 instead of ntpd.

Why does that document instruct to install ntpd?

Is there any reason not to use (or recommend) Chrony?

According to the ambari code base both "ntp" and "chrony" are fine any of these services are fine.

https://github.com/apache/ambari/blob/release-2.6.2/ambari-agent/src/main/python/ambari_agent/HostIn...

.

I see that there are few code changes made recently to also include the : https://issues.apache.org/jira/browse/AMBARI-18761

Doc can be enhanced.
