Hi,

In elasticsearch 2.3, I have set up master eligible node by setting;

```
node.client: false
node.data: true

```

But in elasticsearch 5, I am getting error like

```
unknown setting [node.client]

```

How can I fix this, or how can I make a master eligible node (i would like to setup a cluster of 3 ME nodes) in elasticsearch 5?

As Mark pointed out, the `node.client` setting has been removed as it is redundant. A client node is basically a node that has `node.data` and `mode.master` both set to `false`.

Ok.. So do my settings make it a master eligible node?

Setting `node.master` to `true` will make the node master eligible whether it holds data or not.
