I just saw this after an office move. The servers were offline for a while.

 

This is what I did for our CentOS Linux servers (similar, but not the same, steps would work for Ubuntu/Debian):

 

* verified/updated the /etc/ntp.conf file to be the same across the cluster

* stopped the ntp daemon: /etc/init.d/ntpd stop

* connected to the ntp server named in the ntp.conf file: ntpupdate <ntp_server>

* started the ntp daemon: /etc/init.d/ntpd start

* added ntpd to the startup manager: chkconfig add ntpd

* set ntpd to start in default reunlevels: chkconfig ntpd on

 

This cleared the offset issue. If this doesn't do it for you, you might also have to look into drift, or dig deeper into the time synchronization.

    Thanks a lot for you detailed answer. 

     

    I deleted the cluster and rebuilt it from scratch. Now, it is working fine.(Fingers crossed)

     

    But, It seems, your procedure would definitely solve the problem.

    I had to restart Cloudera SCM Agent to fix this alert after NTP reconfiguration:

    service cloudera-scm-agent restart

      I use puppet and foreman to configure each system the same for all ntp
      clients to a central ntp server.

      Great information here

      If you are facing issue Clock offset issue then there will be problem with your ntp is not in sync.

       

      To resolve follow some commands

       

      Check in which host it is giving problem go under that host through CLI and

       

      1. systemctl status ntpd.service (For checking the status, if its not working the it showing Inactive message)

       

      2. route -n copy the ntp server ip address (You will find under Destination column) 

       

      3. ntpdate <ntp server ip address>

       

      4. systemctl start ntpd.service (for starting & syncing your host, after firing wait for sometime)

       

      5. ntpstat (for checking whether it is synchronized or not it should be in synchronized)

       

      after performing above steps your Clock offset issue will get resolved.

       

      Regard,
