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} [systest@yj52s ~]$ /usr/java/jdk1.7.0_67-cloudera/bin/java -cp $(hadoop classpath):.
