Subject Re: Field Collapsing SOLR-236
Date Wed, 23 Jun 2010 09:39:42 GMT
Hi,
        I checked out modules & lucene from the trunk.
Performed a build using the following commands
ant clean
ant compile
ant example

Which compiled successfully.


I then put my existing index(using schema.xml from solr1.4.0/conf/solr/) in
the multicore folder, configured solr.xml and started the server

When i type in http://localhost:8983/solr

i get the following error:
org.apache.solr.common.SolrException: Plugin init failure for [schema.xml]

Then i picked up an existing index (schema.xml from solr1.3/solr/conf) and
put it in multicore folder, configured solr.xml and restarted my index

Collapsing worked fine.

Any pointers, which part of schema.xml (solr 1.4) is causing this exception?

Regards,
Raakhi
