I have a 2 node elasticsearch cluster (version 1.7.1), let's call it A and B. A is data node, B is data and master node.  
A:

```auto
node.master: false
node.data: true
discovery.zen.ping.unicast.hosts: ["A", "B"]

```

B:

```auto
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["A", "B"]

```

Node B went down and is not recoverable, node A was working OK until first restart. Now cluster state is 503 and logs show `No route to host`. If I change `node.master: true` node status is 200 but all the data is lost. Is there any way to recover data on a single node? I have data directory from node A.
