Hi,
I'm a bit stuck here. I had Solr4.4 working without too many issues. I
wanted to enable the DIH so I firstly added these lines to the
solrconfig.xml:
<lib dir="../contrib/dataimporthandler/lib" regex=".*\.jar" />
<lib dir="../dist/" regex="apache-solr-dataimporthandler-.*\.jar" />
Restarted and everything was fine. Then I added these lines to the config as
well which broke Solr:
<requestHandler name="/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">/opt/solr/collection1/conf/data-config.xml</str>
</lst>
</requestHandler>
This is the error it gives me:
HTTP ERROR 500
Problem accessing /solr/. Reason:
{msg=SolrCore 'collection1' is not available due to init failure:
