Registered to a SCOTTY file transfer nobody runs; in practice it is Hadoop HttpFS, a REST gateway into HDFS.
IANA holds 14000 as scotty-ft, "SCOTTY High-Speed Filetransfer", registered in 2007. What you actually meet on this port is Apache Hadoop's HttpFS: a Tomcat-hosted server that exposes the full WebHDFS REST API — read and write — so clients outside the cluster can reach HDFS through one host instead of talking to every DataNode. Its documented default is http://httpfs-host:14000/webhdfs/v1/..., and it is deployed as the file-access front door for clusters behind a firewall. On a Hadoop node, 14000 means HDFS is reachable over HTTP.
Do not expose
HttpFS is filesystem access to the cluster. Without Kerberos it accepts a user.name query parameter as identity, which is not authentication. Keep it internal and enable secure mode.
