Welcome.

Just keep the default values when you have a small cluster (here 3 nodes).
All nodes will be data and master. Which is fine.

Thanks ....
So you are saying all nodes should be master/data .
node.master=true
node.data=true in all three servers
If i use two master and one data in that case is it fine ????

No it's not fine if you have only one data node.
