Hi [~markrmiller@gmail.com],
Sorry for bothering you, but does the current patch looks okay? Any idea if we can commit this patch now or it needs further refining/work?

> We were experiencing many "No live SolrServers available to handle this request" exception, even though we saw no outages with any of our servers.
> It turned out the actual exceptions were related to the use of wildcards in span queries (and in some cases other invalid queries or usage-type issues). Traced it back to LBHttpSolrClient which was wrapping all exceptions, even plain SolrExceptions, in that outer exception.
> Instead, wrapping in the out exception should be reserved for true communication issues in SolrCloud, and usage exceptions should be thrown as is.
