I am unable to use Kudu and getting some error messages:

The Kudu documentation on the subject suggests your ntp installation may need some troubleshooting. Interestingly, the max error you're seeing (10,000,016 microseconds or just past 10 seconds) is very close to the max error allowable (exactly 10 seconds). What you could do is configure your Kudu service with something like --max_clock_sync_error_usec=11000000 (11 seconds), and that should be good enough for your ntp installation. You'd need to put this in the Kudu service's safety valve configuration since --max_clock_sync_error_usec is not exposed as a first class configuration parameter in CM.
