---------------------------------
Summary: Wrong HttpFS test command in doc
Key: HDFS-11174
URL: https://issues.apache.org/jira/browse/HDFS-11174
Project: Hadoop HDFS
Issue Type: Bug
Components: documentation, httpfs
Affects Versions: 2.6.0
Reporter: John Zhuge
Assignee: John Zhuge
Priority: Minor
There are 2 errors in section {{Test HttpFS is working}} in
http://hadoop.apache.org/docs/r2.7.3/hadoop-hdfs-httpfs/ServerSetup.html:
{noformat}
~ $ 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"}
{noformat}
# The URL path should be {{/webhdfs/v1}}.
# The {{op}} should be {{gethomedirectory}}, not {{homedir}}.
The curl command would produce this error:
{noformat}
$ curl 'http://localhost:14000/webhdfs/v1?op=homedir&user.name=hdfs'
{
"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"
}
}
{noformat}
The correct command should be:
{code}
curl 'http://localhost:14000/webhdfs/v1?op=gethomedirectory&user.name=hdfs'
{
"Path" : "/user/hdfs"
}
{code}
