http://localhost:50070 does not work HADOOP

Question

I already installed Hadoop on my machine \"Ubuntu 13.05\" and now I have an error when browsing localhost:50070 the browser says that the page does not exist.

Answer 1

port 50070 changed to 9870 in 3.0.0-alpha1

In fact, lots of others ports changed too. Look:

Namenode ports: 50470 --> 9871, 50070 --> 9870, 8020 --> 9820
Secondary NN ports: 50091 --> 9869, 50090 --> 9868
Datanode ports: 50020 --> 9867, 50010 --> 9866, 50475 --> 9865, 50075 --> 9864
