             Summary: Add capture-output to Spark actions
                 Key: OOZIE-3556
                 URL: https://issues.apache.org/jira/browse/OOZIE-3556
             Project: Oozie
          Issue Type: New Feature
            Reporter: Amit Kumar


It is very common to want to reuse the result of a Hive query in another action.  
It will be useful if we can capture output of a Hive action the same way we do for shell actions - if the output is in the format of "key=value" use it for capture output.

Even more useful:
* Parse "key \t value" as "key=value" - this will allow capturing result of "describe table"
* Possibly capture all results as "Hive=<result>", up to maximum length. This will require user parsing but will give maximum flexibility.
