Github user JonathanRider commented on the issue:
Just ran it on quickdev where I set the es.host in the global json file to
"node2,node1" where node2 doesn't exist as it is a single node vagrant.
Using my patch, it writes to ES without a problem as it fails to use node2,
so it switches to node1.
I then compiled master and did the same thing and received this error since
node2 doesn't exist and it fails to use the second host.:
