Cell발생시 조치사항

총관리자 2017.07.05 15:31 조회 수 : 57

halyard 1.3에서 rdf4j-server.war와 rdf4j-workbench.war를 tomcat의 webapps에 deploy한후 Repositories->new repository해서 새로운 repository를 생성한후 Explore->Namespaces메유를 조회시 java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/Cell 오류가 발생할 수 있는데 이는 halyard가 hbase에 triple data를 저장하는데 필요한 hbase의 라이브러리를 인식히지 못해서 발생하는 문제다.

이를 해결하기 위해서 Tomcat의 bin 디렉토리에 setenv.sh파일을 만들어 아래의 내용을 넣고 권한을 755로 부여한후 tomcat를 다시 기동해주면 된다.

------------------setenv.sh내용----------

export CLASSPATH="$CATALINA_HOME/lib/servlet-api.jar:"`hadoop classpath`:`$HOME/hbase/bin/hbase classpath

------------------------------오류내용--------------------------------------
