-----------------------------------------------------------
This issue has been fixed in upstream Docker. Once it makes it into a Docker
release I think it's reasonable to document a minimum version of Docker we
support Kudu running on due to this issue.

> Key: KUDU-2000
> URL: https://issues.apache.org/jira/browse/KUDU-2000
> Project: Kudu
> Issue Type: Task
> Components: documentation
> Affects Versions: 1.3.1
> Reporter: Mike Percy
>
> When running Kudu in a Docker container, Kudu currently requires the
> CAP_SYS_TIME capability (or running the docker container with the
> --privileged flag).
> If run with default privileges, calling ntp_gettime() results in an EPERM
> error that apparently comes from adjtimex(). In that case, the resulting
> fatal error from HybridTime looks like the following in the logs:
> {code}
> F0508 22:36:35.687885 1 master_main.cc:68] Check failed: _s.ok() Bad
> status: Service unavailable: Cannot initialize clock: Error reading clock.
> ntp_gettime() failed: Operation not permitted
