> Per the
> [spec|https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/WebHDFS.html#Get_Home_Directory],
> WebHDFS provides a REST endpoint for getting the user's home directory:
> {noformat}Submit a HTTP GET request.
> curl -i "http://<HOST>:<PORT>/webhdfs/v1/?op=GETHOMEDIRECTORY"{noformat}
> However, WebHDFSFileSystem.java does not use this, instead building the home
> [directory
> locally|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/web/WebHdfsFileSystem.java#L271]:
> {code} /** @return the home directory. */
> public static String getHomeDirectoryString(final UserGroupInformation ugi)
> {
> return "/user/" + ugi.getShortUserName();
> }
> @Override
> public Path getHomeDirectory() {
> return makeQualified(new Path(getHomeDirectoryString(ugi)));
> }{code}
> The WebHDFSFileSystem client should call to the REST service to determine the
> home directory.
