Shawn Heisey commented on SOLR-8042:
------------------------------------
Here's the user's code from the mailing list:
{code}
CollectionAdminRequest.Reload reloadReq = new
CollectionAdminRequest.Reload();
reloadReq.process(client, collection);
{code}
The process method that the user code is calling is on the request object.
This ends up as SolrRequest#process ... which uses the request method on the
client object. The CloudSolrClient#request method appears to be where the
disconnect starts, and I think the root of the problem is that the
implementation of the request (likely in CollectionSpecificAdminRequest) does
not have a facility for setting the collection, except with a "name" parameter.
Side issue: The definition of ADMIN_PATHS looks like it is misplaced in
CloudSolrClient. It should be near the top of the class, with the other fields.
