Hi folks,
I'm trying to connect to a NameNode using Hadoop's RPC ClientProtocol
class. Code below:
InetSocketAddress address = new InetSocketAddress("namenode", 9000);
Configuration conf = new Configuration();
ClientProtocol client =
(ClientProtocol) RPC.waitForProxy(ClientProtocol.class,
ClientProtocol.versionID, address, conf);
System.out.println(client.getStats());
Unfortunately, my currently logged in user name is not the user who's
configured on the server; hence the following exception:
org.apache.hadoop.ipc.RemoteException:
org.apache.hadoop.security.AccessControlException: Access denied for
user mike. Superuser privilege is required
Is there a configuration property key I can set in the configuration
object to override the system username?
Thanks.
