The host's NTP service is not synchronized to any remote server.

The host's NTP service is not synchronized to any remote server.

Explorer

Hi,

 

 I'm getting error "The host's NTP service is not synchronized to any remote server." in CDH5.5. I have installed CDH5.5 on ubuntu14.04 on AWS EC2. I did installed NTP, configured ntp.conf with no luck. Please let me know how to resolve this issue? 

 

Thanks 

Ravi

Does your EC2 instance have connectivity to the NTP servers it is configured with?  Maybe the security group is not open?

 

Try stopping your ntp service and running the command:

 

ntpdate -s <address_of_ntp_server>

 

Does that work?  I have seen in the past where ntp fails to automatically synchronize the clock if the original clock value is too far off.  Forcing it to set it using ntpdate, then starting up ntp again, should fix it.  Of course, all of this depends on connectivity to the ntp server...
