Paul Rütter (BlueConic) commented on CASSANDRA-16555:
-----------------------------------------------------
We've successfully used our custom implementation on an AWS EC2 instance with
the metadata service v1 disabled.
We also supplied a v2 version of the Ec2MultiRegionSnitch, although we haven't
been able to test this one ourselves.
> Add out-of-the-box snitch for Ec2 IMDSv2

> In order to patch a vulnerability, Amazon came up with a new version of their
> metadata service.
> It's no longer unrestricted but now requires a token (in a header), in order
> to access the metadata service.
> See
> [https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html]
> for more information.
> Cassandra currently doesn't offer an out-of-the-box snitch class to support
> this.
> See
> [https://cassandra.apache.org/doc/latest/operating/snitch.html#snitch-classes]
> This issue asks to add support for this as a separate snitch class.
> We'll probably do a PR for this, as we are in the process of developing one.
