Deploying hadoop cluster

[#1]

I want to set up hadoop cluster where i want master node and few slave node to be in some country and remaining slave nodes sitting in different country. Is it possible to deploy this? Is there any article or tutorial which might help me to get the solution.

Of course that possible. This doc could help you Topology scripts are used by Hadoop to determine the rack location of nodes

Topology configuration

This! You can but you shouldn't. Cross-datacenter hadoop clusters do not perform. Don't do it.

Use data replication software like DistCP or Falcon to sync clusters in different data centers instead.

Do not do it! @Kabirdas B K

I don't recommend doing this. It's possible but not the best practice. You can setup DR using Falcon or WanDisco.
