> Project: Oozie
> Issue Type: Bug
> Components: core
> Affects Versions: 5.1.0
> Reporter: Denes Bodo
> Assignee: Denes Bodo
> Priority: Critical
> Labels: performance
> Attachments: OOZIE-3561-002.patch, OOZIE-3561-003.patch,

> 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
