This is how I added my custom action jar to oozie : - stoped oozie - added classname to oozie.service.ActionService.executor.ext.classes in oozie-site.xml - copy cutom.jar to /usr/hdp/current/oozie-server/libext/. </P><P>- /usr/hdp/current/oozie-server/bin/oozie-setup.sh prepare-war - started oozie back Error : </P><PRE>java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/CustomActionClass at ... ...</PRE> I understand that new actions are to be added as ext.classes and action jars in libext folder. Am I missing something here ? Also how are libext jars different from sharelib jars ?
