http://localhost:50070 does not work HADOOP
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.
Solution 1:
Since Hadoop 3.0.0 - Alpha 1 there was a Change in the port configuration:
http://localhost:50070
was moved to
http://localhost:9870
see https://issues.apache.org/jira/browse/HDFS-9427
Solution 2:
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

Solution 3:
First, check that java processes that are running using "jps". If you are in a pseudo-distributed mode you must have the following proccesses:
- Namenode
- Jobtracker
- Tasktracker
- Datanode
- SecondaryNamenode
If you are missing any, use the restart commands:
$HADOOP_INSTALL/bin/stop-all.sh
$HADOOP_INSTALL/bin/start-all.sh
It can also be because you haven't open that port on the machine:
iptables -A INPUT -p tcp --dport 50070 -j ACCEPT
Solution 4:
- step 1 : bin/stop-all.sh
- step 2 : bin/hadoop namenode -format
- step 3 : bin/start-all.sh
