-----------------------------------

             Summary: httpfs doesn't work with creates from a jar with kerberos
                 Key: HDFS-8337
                 URL: https://issues.apache.org/jira/browse/HDFS-8337
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: HDFS, hdfs-client
            Reporter: Yongjun Zhang
            Assignee: Yongjun Zhang


In a secure cluster, running a simple program:

{code}
import org.apache.hadoop.conf.*; 
import org.apache.hadoop.fs.*; 
import org.apache.hadoop.security.*;
class Foo { 
  public static void main(String args[]) throws Exception { 
    FileSystem fs = FileSystem.get(new java.net.URI("webhdfs://<host>:14000/"), new Configuration()); 
    System.out.println(fs.listStatus(new Path("/"))[0]); 
    java.io.OutputStream os = fs.create(new Path("/tmp/foo")); 
    os.write('a'); 
    os.close(); 
  } 
} 
{code}

Basically to access httpfs via webhdfs, the following exception is thrown:

{code}
