Subject: Simple authentication
Hi,
I am trying to connect to my remote hadoop instance through a java client.
public static void main(String[] args) {
try {
UserGroupInformation ugi =
UserGroupInformation.createRemoteUser("vagrant");
ugi.doAs(new PrivilegedExceptionAction<Void>() {
public Void run() throws Exception {
Configuration conf = new Configuration();
// conf.set("fs.defaultFS",
"hdfs://10.1.10.213:8042/user/test");
conf.set("hadoop.job.ugi", "vagrant");
FileSystem fs = FileSystem.get(conf);
fs.createNewFile(new
Path("user/test/test-file"));
FileStatus[] status = fs.listStatus(new
Path("/user/test"));
for(int i=0; i<status.length; i++)
System.out.println(status[i].getPath());
return null;
}
});
} catch(Exception e) {
e.printStackTrace();
}
}
When I execute this I get the following exception.
Caused by:
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException):
SIMPLE authentication is not enabled. Available:[TOKEN]

org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:232)

I have hadoop.security.authentication set to simple and
hadoop.security.authorization set to false in core-site.xml on my remote hadoop
instance. What am I doing wrong? Any help is much appreciated.
Best regards,
