IP addresses of various daemons in Hadoop’s pseudo-distributed mode… here is a solution to the problem.
IP addresses of various daemons in Hadoop’s pseudo-distributed mode
I have installed Hadoop 2.7.1 in pseudo-distributed mode. What is the IP of the following daemon:
IP address of Namenode?
IP address of Datanode?
IP address of Resource Manager?
IP address of Node Manager?
The /etc/hosts file on my machine reads as follows:
127.0.0.1 localhost
127.0.1.1 linuxPC
linuxPC is the name of my machine.
Solution
For pseudo-distributed, use localhost for all daemons. 127.0.0.1 is the standard IP used for localhost.
If you need to access the cluster from outside the host, use the actual IP address of the host.
