Solr+SolRDF solrdf초기 기동시 "Caused by: java.lang.IllegalAccessError: tried to access field org.apache.solr.handler.RequestHandlerBase.log from class org.gazzax.labs.solrdf.handler.update.RdfUpdateRequestHandler" 오류가 발생시 조치사항
아래와 같이 "Caused by: java.lang.IllegalAccessError: tried to access field org.apache.solr.handler.RequestHandlerBase.log from class org.gazzax.labs.solrdf.handler.update.RdfUpdateRequestHandler"오류가 발생하는 경우가 있는데
이는 solrdf 1.1.0이 실행되는 solr의 버젼이 up되면서 내부적인 처리방법이 변경되면서 발생하는 문제임
==========> solrdf 1.1와 어울리는 solr의 버젼을 5.3.1로 맞춰서 설치해줘야 함
