# WHATPORT(14000)

## NAME

port 14000 — Hadoop HttpFS (in practice) / scotty-ft (IANA) — Registered to a SCOTTY file transfer nobody runs; in practice it is Hadoop HttpFS, a REST gateway into HDFS.

Protocol: TCP  
IANA registry

## DESCRIPTION

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.

## EXPOSURE

**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.

## CHECK

```sh
curl -s -o /dev/null -w '%{http_code}\n' "http://TARGET:14000/webhdfs/v1/?op=LISTSTATUS"
```
