Riak's HTTP client interface, the counterpart to Protocol Buffers on 8087.
Riak KV's security guide lists TCP 8098 as the HTTP client port that every client must be able to reach, alongside 8087 for the Protocol Buffers interface. The HTTP API answers REST-shaped requests for buckets, keys and cluster status, which makes it easy to identify with curl. IANA leaves 8098 Unassigned, so a listener here that answers HTTP with Riak JSON is a Riak node. Authentication and TLS are opt-in and disabled by default.
Do not expose
A default Riak node grants full read and write access over cleartext HTTP to anyone who can open the socket.
