Hi,

We have planned an architecture of Elasticsearch with 3 master nodes, 4 data node and 2 client nodes.

Now for configuring the client node, in the configure file of elasticsearch, I added the lines

node.master: false  
node.data: false

and for Data node

node.master: false

Now, after doing this configuration, the problem occurs is that, these nodes are no more shown in the clusters. Even I am not able to telnet these nodes.

How can I resolve this issue?
