Jacek Lewandowski commented on CASSANDRA-16555:
-----------------------------------------------

Left some comments . I like the idea of having separate implementation for 
released Cassandra versions. Though, I think it may be worth refactoring that 
towards better code reuse for trunk

> 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.
