Description
There are 2 errors in section Test HttpFS is working in http://hadoop.apache.org/docs/r2.7.3/hadoop-hdfs-httpfs/ServerSetup.html
~ $ curl -i "http://<HTTPFSHOSTNAME>:14000?user.name=babu&op=homedir"
HTTP/1.1 200 OK
Content-Type: application/json
Transfer-Encoding: chunked
{"homeDir":"http:\/\/<HTTPFS_HOST>:14000\/user\/babu"}
- The URL path should be /webhdfs/v1.
- The op should be gethomedirectory, not homedir.
The curl command would produce this error:
$ curl 'http://localhost:14000/webhdfs/v1?op=homedir&user.name=hdfs' | json_pp
{
"RemoteException" : {
"message" : "java.lang.IllegalArgumentException: No enum constant org.apache.hadoop.fs.http.client.HttpFSFileSystem.Operation.HOMEDIR",
"exception" : "QueryParamException",
"javaClassName" : "com.sun.jersey.api.ParamException$QueryParamException"
}
}
The correct command should be:
$ curl 'http://localhost:14000/webhdfs/v1?op=gethomedirectory&user.name=hdfs' | json_pp { "Path" : "/user/hdfs" }
