> This is a tracking ticket for known issues of running Kudu on OS X.
>  # -The hybrid logical clock has error permanently set to 0us. This is a result of the {{ntp_gettime}} (or similar) API not existing on Darwin. The result is that using the hybrid logical clock on a cluster of OS X hosts is unsupported (a single-host Kudu installation is fine).- 
> UPDATE: with macOS High Sierra (10.13), the hybrid clock is now supported for Kudu 1.12 and newer
>  # The Kudu client library does not properly hide non-public symbols. This is a result of the {{--version-script}} option being unavailable on the OS X system linker.
>  # The log block manager is not supported on OS X. This is a result of OS X not supporting sparse files and hole punching.
>  # Some of the monitoring and debugging tools built in to Kudu do not work properly. In particular, stack traces (both user and kernel) may not work, and the {{/pprof}} endpoint on server pages may not work correctly.
>  # ASAN tests will run and flag issues correctly, but LSAN is disabled (it is Linux only), and there are many false positives.
