             Summary: Forkjoin validation is slow when there are many actions in chain
                 Key: OOZIE-3561
                 URL: https://issues.apache.org/jira/browse/OOZIE-3561
             Project: Oozie
          Issue Type: Bug
          Components: core
    Affects Versions: 5.1.0
            Reporter: Denes Bodo
            Assignee: Denes Bodo


In case we have a workflow which has, let's say, 80 actions after each other:
{{a1 -> a2 -> ... a80}}
then the validator code "never" finishes.

Currently the validation (in my understanding) does depth first checks from the start node and runs in time of n! . This is confirmed as when we split this huge workflow into two 40-element workflow then we get 2x ~40!-step in validation instead of ~80! steps.

Guys, could you please confirm or disprove my theory?

Thanks
