I was using Solr 4.0 but ran into a few problems using SolrCloud. I'm trying out 4.1 RC1 right now but the update URL I used to use is returning HTTP 404.
For example, I would post my document updates to, http://localhost:8983/solr/collection1 But that is 404ing now (collection1 exists according to the admin UI, all shards are green and happy, and data dirs exist on the nodes). I also tried the following, http://localhost:8983/solr/collection1/update And also received a 404 there. A specific example from the Java client: 22:38:12.474 [pool-7-thread-14] ERROR com.massrel.faassolr.SolrBackend - Error while flushing to Solr. org.apache.solr.common.SolrException: Server at http://backfill-2d.i.massrel.com:8983/solr/15724/update returned non ok status:404, message:Not Found at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:372) ~[solr-solrj-4.0.0.jar:4.0.0 1394950 - rmuir - 2012-10-06 03:05:44] at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:181) ~[solr-solrj-4.0.0.jar:4.0.0 1394950 - rmuir - 2012-10-06 03:05:44] at org.apache.solr.client.solrj.impl.LBHttpSolrServer.request(LBHttpSolrServer.java:438) ~[solr-solrj-4.0.0.jar:4.0.0 1394950 - rmuir - 2012-10-06 03:05:44] at org.apache.solr.client.solrj.request.AbstractUpdateRequest.process(AbstractUpdateRequest.java:117) ~[solr-solrj-4.0.0.jar:4.0.0 1394950 - rmuir - 2012-10-06 03:05:44] But I can hit that URL with a GET, $ curl http://backfill-1d.i.massrel.com:8983/solr/15724/update <?xml version="1.0" encoding="UTF-8"?> <response> <lst name="responseHeader"><int name="status">400</int><int name="QTime">2</int></lst><lst name="error"><str name="msg">missing content stream</str><int name="code">400</int></lst> </response> Thoughts? Thanks.
