My elasticsearch cluster(version 2.0) is started and the node client is built successfully, but for some reason I'm getting the following error while running queries using node client.

I've even disabled the "multicast" as per this [post](https://groups.google.com/forum/embed/#!topic/elasticsearch/uNRGDdwAi-g) - still no luck. Surprisingly, I could access the elasticsearch from sense. Any clues on what is going wrong ?

It would be useful for other users who might experience this issue in the future if you could explain how you resolved the issue?

I take back from statement: I'm still getting the exception ☹ Please help. This is the latest exception:
