Installed, Connected, But Not Indexing

ERROR:unknown field 'site'type --- this usually means that schema.xml isn't in the right place in the Solr installation. The schema.xml file from the Drupal module needs to be copied into the conf directory of your Solr server before the server is started. Are you sure you've done this?

I also get this issue that the index is not passed to SOLR. If I check the logs, it gives me the following:

Indexing failed on one of the following nodes: 4, 5, 27, 90, 45, 101, 100, 92, 93, 99, 89, 98, 94, 97, 67, 91, 102, 23, 43, 105 
"400" Status: Bad Request


Error 400 

HTTP ERROR: 400ERROR:unknown field 'site'
RequestURI=/solr/updatePowered by Jetty:// 

hmm, several reboots of Jetty saved the day...

Have the same error message. I have checked - everything is installed properly. I have functioning multisite core, the other sites have been indexed with no issues, but on just one particular website indexing always stops at the same one place - when it reaches 10%. Restarting solr severa times did not solve the problem like it did for zualas.

I guess one of my nodes is a problem. But which one? How can I identify the node which prevents indexing?

I had the same problem but the solution was easy.

Varnish was automatically downloaded with mercury.
The solconfig.xml and schema.xml were not present in my automatically drush downnloaded apachesolr module folder.

So I downloaded apachesolr again from drupal.org and there the schema.xml and solrconfig.xml were present.
Replacing these and restarting the solr did solve the problem.

I guess if you drush dl from within varnish these 2 config files are not included?
Problem solved here.
Great module by the way!
