Actually, I had tried the instanceDir="ckan" but it didn't work either (with the same error, just reporting a wrong path to solrconf.xml). I used this configuration taking suggestion from here http://stackoverflow.com/questions/16230493/apache-solr-unable-to-access-adm in-page). But now that I have commented the dataDir setting in solrconf.xml as you suggest, it changes behaviour and i have a different error from Solr Logging:SolrCore Initialization Failures ckan-schema-2.0: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error loading class 'solr.clustering.ClusteringComponent' Please check your logs for more information Log4j (org.slf4j.impl.Log4jLoggerFactory) Time Level Logger Message 17:36:43 WARN SolrResourceLoader Can't find (or read) directory to add to classloader: ../../../contrib/extraction/lib (resolved as: /usr/share/solr/ckan/../../../contrib/extraction/lib).
Your solrconfig.xml file includes the ClusteringComponent, but you don't have the jars required for that component available. Your solrconfig file does have a bunch of <lib> directives, but they don't point anywhere that's valid -- they assume that the entire Solr download is available, not just what's in the example dir. The jar for that particular component can be found in the download as dist/solr-clustering-X.X.X.jar ... but it is likely to also require additional jars, such as those found in contrib/clustering/lib.
When it comes to extra jars for contrib or third-party components, the best thing to do is remove all <lib> directives from solrconfig.xml and put the jars in ${solr.solr.home}/lib. For you that location would be /usr/share/solr/lib. Solr automatically looks in this location without any extra configuration.
Further advice - remove things you don't need from your config. If you're not planning to use the clustering component, take it out. Also remove any handlers that refer to components you won't be using -- the /browse handler is a prime example of something that most people don't need.
Thanks, Shawn
