Reply To: How to add new node in hadoop cluster ?

Hi,

first you need to add your new host

http://docs.hortonworks.com/HDPDocuments/Ambari-2.1.1.0/bk_Ambari_Users_Guide/content/_adding_hosts_to_a_cluster.html

then you’ll need to install a datanode on this host which is quite easy rtough the ambari interfaces. You’ll have to select the host then action add datanode.

however since you’re working directly on the sandbox, I think you’ll have to reconfigure the network of the virtual machine.
