Hi,

What command did you ran to see that the other nodes are running or not?

Did you start the services after you installed Hadoop? To start the services go to the bin folder inside the hadoop and run the below command:

$ ./start-all.sh

If you are using Hadoop version-2.7.7, then I would like to suggest one more solution.

Run the command 

hadoop namenode -format

Once the namenode is formatted, go to Hadoop-2.7.7/sbin directory and start all daemon with the command​

/start-all.sh

After this, check that all your Hadoop daemons are running or not, with this command 

 jps

I hope it will help.
