Jakob Furrer updated SOLR-6542:
-------------------------------
Description:
I try to get a HttpSolrServer object with the following non-standard
functionalities:
* a proxy is used for the connection
* the connection timeout is set
A HttpClient object is required for setting proxy (see code listing 1).
The timeout can either be defined on the internal httpClient object (see option
a) or later on the created httpSolrServer object (see option b)
Question one:
_Is there a difference in behaviour of the HttpSolrServer instance when I set
the connection timeout directly in my own HttpClient object in comparison to
using the method HttpSolrServer#setConnectionTimeout() ?_
I would expect that there is no difference.
Moving from Solr 4.6 to Solr 4.9, I also upgraded HttpClient to the same
Version Solr is using (httpclient-4.2.6 was used in solr-4.6, now
httpclient-4.3.1 is used in solr-4.9).
The newer version of HttpSolr deprecates a number of methods used in my code,
therefore I was looking for a way to modify it according to the new API (see
code listing 2).
I now get an java.lang.UnsupportedOperationException when using the method
HttpSolrServer#setConnectionTimeout()
{noformat}
java.lang.UnsupportedOperationException

org.apache.http.impl.client.InternalHttpClient.getParams(InternalHttpClient.java:204)

at
test.HttpSolrServerTest.newStyle_httpclient_4_3_1(HttpSolrServerTest.java:89)
{noformat}
It seems that since the switch of the library HttpClient something internally
clashes in the HttpSolrServer object.
Question two:
_Is this something that has been overlooked when the library within SolrJ was
changed to the newer version, or am trying something that must not be done?_
I would expect that the method HttpSolrServer#setConnectionTimeout() can be
used, independent of the way I chose to create that object.
Bonus question:
_Am I using an acceptable way of accessing Solr over a proxy or are there
better methods?_
