Steve Davids updated SOLR-5700:
-------------------------------
Attachment: SOLR-5700.patch
Created a new patch that always consumes the response's HttpEntity and cleaned
up the test a little.
After applying the patch to the trunk there was only one error that occurred
for me:

I believe the the OverseerRolesTest is a known flakey test associated with
SOLR-5476.

> In this case, the request handler threw an exception, and all the user got
> back was an error code, no message. They would actually have to dig through
> the logs on the remote machine to the see the error.
> I tried for a bit to get the error message with HttpURLConnection, but wasn't
> successful. Instead, I used httpclient, like SolrServer uses. This works,
> as SolrServer already gives reasonable error messages.
> This approach of using httpclient has another advantage as well: because the
> httpclient is created via the HttpClientUtil in the same way as the other
> http clients, any configuration settings are automatically picked up. For
> example, I have an HttpClientConfigurer that I wrote to handle kerberos
> connections; with this approach, the forwarded requests just work with
> kerberos. With the old approach, I would have to modify the remoteQuery code
> to do kerberos-specific things.
