Issue with SniffingConnectionPool and non-http nodes

[EricKeij]

We ran into an issue when using the SniffingConnectionPool and having a node in the cluster with http disabled. This gives an exception saying "Failed sniffing cluster state". Looking at the inner exception it turns out that the actual error occurs in ParseToUri() in SniffResponse which executes a regex getting an empty httpAddress passed in.

The issue does not occur when stopping non-http nodes or when using the StaticConnectionPool and explicitly specify the nodes.

We are using NEST 2.0.4 and ES 2.2.0.

Argh, yeah none of our unit tests test this scenario. Thanks for opening this issue 👍

Hi @EricKeij finally got around to fixing this as per: #2078

Should make it in Nest 2.4 which should be out either end of this week or next week.
