Robert Muir updated SOLR-4088:
------------------------------
Attachment: SOLR-4088_unknown_host.patch
Here's the patch i'm testing locally.
The problem is when the host is configured as null, there are heuristics to
guess how the host should be advertised.
basically the patch just handles the situation where the first heuristical
method (resolving the hostname from the system) fails, which can happen, e.g.
if DNS is not functioning.
In this case we just fall through to the logic below, of iterating interfaces.
> ZkController baseURL only get the host name not address, will occur can't get
> the right URL to do recovery.
