             Summary: remove <lib> configurations from solrconfig.xml and eliminate per core class loading
                 Key: SOLR-6681
                 URL: https://issues.apache.org/jira/browse/SOLR-6681
             Project: Solr
          Issue Type: Improvement
            Reporter: Noble Paul


As Solr moves more towards cloud ,solrconfig is stored in Zookeeper. Storing the local library information in a file stored in a remote and common location for all nodes make no sense. 
In this new world, cores are created and managed by the solrcloud system and  there is no need to have separate classloading for each core and a lot of unnecessary classloading issues in solr can go away

Going forward, all cores in a node will have only one classpath. We may define a standard directory such as 'ext' under the HOME and let users store all their jars there
