I have one clouster on Centos7.The servers's ntp service works well.But I got the error message "
How to solve it ,Thanks.
If ntpd is down, I would expect the clock offset health check to complain, too.
In order to determine offset, the Cloudera agent on each host will run "ntpdc -np" every 10 seconds (if I recall).
The output is then parsed so that if no line starts with an "*", that means ntpd is not synchronized with any NTP server.
If a "*" is found in front of a row, then the offset column is parsed to determine the offset.
I would try running: ntpdc -np
If you don't see an "*" in front of a row, then that means ntpd is running, but it cannot connect to an NTP server.
I think Its cause is that Chrony is running on CentOs7 default,one program same as ntpd .After the
After the ntpd program ininstalled .Clock offset warnning message disappear.
