Registered to Teradata, used in practice as yet another alternate HTTP port.
IANA assigns 8002/tcp and /udp to teradataordbms, the Teradata database. Outside Teradata shops the registration means little: 8002 is part of the 8000-8100 band that application servers, containers and dev tooling occupy when 8000 and 8001 are taken, so a scan hit is usually plain HTTP. Nmap's data ranks it as uncommon but not rare. Read the banner before assuming either answer.
Expose with care
Both plausible occupants argue for caution: a database listener should never face the internet, and an HTTP service parked on a high port is often something that assumed a proxy would protect it.
