Shawn Heisey commented on SOLR-8216:
------------------------------------
[~risdenk], the basic problem with node-specific requests in a SolrCloud
context is that you do not know which node will be selected by CloudSolrClient.
In order to guarantee which node(s) I'm talking to, I would do this with
HttpSolrClient. Create an instance of that object for each Solr that you're
running. Here's some sample code:
{code}
SolrClient sysClient = new HttpSolrClient("http://server:port/solr";);
SolrQuery sysQuery = new SolrQuery();
sysQuery.setRequestHandler("/admin/info/system");
QueryResponse rsp = sysClient.query(sysQuery);
String os = (String) rsp.getResponse().findRecursive("system", "name");
String ver = (String) rsp.getResponse().findRecursive("system", "version");
System.out.println("OS: " + os + " " + ver);
{code}
> CloudSolrClient cannot query /admin/info

> Project: Solr
> Issue Type: Bug

> I am trying to use CloudSolrClient to query information about the Solr server
> including version information. I found /admin/info/system and it seems to
> provide the information I am looking for. However, it looks like
> CloudSolrClient cannot query /admin/info since INFO_HANDLER_PATH [1] is not
> part of the ADMIN_PATHS in CloudSolrClient.java [2]. Was this possibly missed
> as part of SOLR-4943?
> As a side note, ZK_PATH also isn't listed in ADMIN_PATHS. I'm not sure what
> issues that could cause. Is there a reason that ADMIN_PATHS in
> CloudSolrClient would be different than the paths in CommonParams [1]?
