> In order to leverage new Hadoop features without reflection based workaround,
> we want to bump the minimum supported version of Hadoop to 2.8.5 (released in
> 2018). There were no reported objections from the community against dropping
> support for older versions.
> Please note that this doesn't break the binary protocol compatibility, which
> means that 2.8.5 client can still talk to older servers.
