• 多workflow间共享jar包
  
  1：需要将要共享的jar包放到指定hdfs目录，如/user/supertool/share/lib/java

  <property>

          <name>oozie.service.WorkflowAppService.system.libpath</name>

          <value>/user/${user.name}/share/lib</value>

          <description>

              System library path to use for workflow applications.

              This path is added to workflow application if their job properties sets

              the property 'oozie.use.system.libpath' to true.

          </description>

  </property>

  2：在oozie-site.xml中加入配置，所有的java action就会将/user/supertool/share/lib/java加入classpath

  <property>

     <name>oozie.action.sharelib.for.java</name>

     <value>java<value>

  </property>

   

  3：在job.properties中设置oozie.use.system.libpath=true

   

  ！！当然也可以在java action中配置此选项，只在本次action中将/user/supertool/share/lib/java加入classpath
