title: Oozie sub workflow action
body: <p>I'm using Oozie for deploying Hadoop workflows. I have a util java action that returns HDFS path based on parameters provided. I'm using capture output property to set the property and retrieve it in subsequent workflow actions. </p>
  
  <p>I would like  to configure this as sub workflow as it is  to be used in different workflows. Is it possible to retrieve action data from a sub workflow in Oozie using EL function ?</p>
