Hi,

Probably I missing something really obvious, but I struggling with  
running elasticsearch in my tests. First I've tried initalizing this  
way:

client =  
NodeBuilder.nodeBuilder().local(true).client(true).build().client();

I expect this will create a working elasticsearch instance ...

But if I try to index a couple of documents, it throws the following  
error:

I've tried various flags setting the 'client' to 'false', but it  
doesn't changed anything.

Can you shed any light on this problem ?

Thanks,

I'm starting my node once per test \*\* and then getting the client from  
it. Something like:

@beforeclass  
Node n = nodeBuilder().local(true).build().start();

@before  
n.client() + cleanup indices

Thanks, the "start" method was missing. It should be in the  
documentation too.

The docs example are with node() call on the node builder, which builds and  
starts the node automatically. Did you see something else somewhere?
