Alexey Serbin updated KUDU-3067:
--------------------------------
Status: Open (was: In Review)
> Inexplict cloud detection for AWS and OpenStack based cloud by querying
> metadata
> --------------------------------------------------------------------------------
>
> Key: KUDU-3067
> URL: https://issues.apache.org/jira/browse/KUDU-3067
> Project: Kudu
> Issue Type: Bug
> Reporter: liusheng
> Assignee: Alexey Serbin
> Priority: Major
>
> The cloud detector is used to check the cloud provider of the instance, see
> [here|#L59-L93]], For AWS cloud it using the URL
> [http://169.254.169.254/latest/meta-data/instance-id|http://169.254.169.254/latest/meta-data/instance-id*]
> to check the specific metadata to determine it is AWS instance. This is OK,
> but for OpenStack based cloud, the metadata is same with AWS, so this URL can
> also be accessed. So this cannot distinct the AWS and other OpenStack based
> clouds. This caused an issue when run
> "HybridClockTest.TimeSourceAutoSelection" test case, this test will use the
> above URL to detect the Cloud of instance current running on and then try to
> call the NTP service, for AWS, the dedicated NTP service is
> "169.254.169.123", but for OpenStack based cloud, there isn't such a
> dedicated NTP service. So this test case will fail if I run on a instance of
> OpenStack based cloud because the cloud detector suppose it is AWS instance
> and try to access "169.254.169.123".
