http://localhost:9870 does not work HADOOP

Question

I am beginner to learn hadoop,i use latest version ubuntu,I have an error when browsing localhost:9870 the browser says that the page does not exist

Answer 1

First, you need to check you Hadoop daemons are running by entering the command: jps. Here my namenode is also configured as datanode.

Second, check Namenode Java Process is running with 9870 port or not by entering the command.

netstat -an | grep 9870

Third, check dfs.namenode.http-address property in hdfs-site.xml

Finally, make sure you have disabled firewall
