Hi,

Just installed 0.19.0 and found a regression in network:host...

network:host : _eth0:ipv4_

used to work, now it yields the following error message:

INFO | jvm 1 | 2012/03/02 07:36:35 | WrapperManager: Initializing...  
INFO | jvm 1 | 2012/03/02 07:36:37 | {0.19.0}: Startup Failed ...  
INFO | jvm 1 | 2012/03/02 07:36:37 | - BindTransportException[Failed  
to resolve host [null]]  
INFO | jvm 1 | 2012/03/02 07:36:37 | IOException[Failed to find  
network interface for [_eth0:ipv4_]]  
STATUS | wrapper | 2012/03/02 07:36:39 | \<-- Wrapper Stopped

Specifying the IP address still works, but the shorthand above was very  
handy.

...Thanks,  
...Ken

Right, opened an issue: [Special host config notation `_[interfaceName]_` might fail to resolve the host address · Issue #1754 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/1754).
