Subject Re: Reload core via CoreAdminRequest doesnt work with solr cloud? (solrj)
Date Mon, 26 Nov 2012 13:51:59 GMT
I think that core admin commands may not work with CloudSolrServer at the moment. There is
a JIRA issue for it I think.

For now, I'd use the HTTP imp and point at the node you want to work with or reload with the
collections api.
