Hi Felix, If you specify the <capture-output> element, you can have Oozie get the output of an action; the output has to be in java properties format and there's a few other restrictions. Try searching http://oozie.apache.org/docs/3.3.1/WorkflowFunctionalSpec.html for <capture-output>; it should be similar to the Java action. You can then use an EL function to pass that output to any of your actions.
Oozie workflows must be DAGs ( http://en.wikipedia.org/wiki/Directed_acyclic_graph) so no loops/cycles are allowed. - Robert On Sun, Mar 3, 2013 at 11:33 PM, Felix.徐 <[email protected]> wrote: > Hi, > > I'm new to oozie and I'm wandering if there is any way to initialize > Action's parameters according to the output of previous Action? > > The scenario is that I have a few hive scripts(A,B,C) > If the output of A is null then I would initialize B's parameter with some > other value. > > Another question is that does oozie support loop action that can invoke > other actions? >
