Duc Anh Le updated OOZIE-1443:
------------------------------
Attachment: workflow.xml
dangling-node.png
> Dangling nodes prevent jobs from succeeding
> -------------------------------------------
>
> Key: OOZIE-1443
> URL: https://issues.apache.org/jira/browse/OOZIE-1443
> Project: Oozie
> Issue Type: Bug
> Reporter: Duc Anh Le
> Priority: Minor
> Attachments: dangling-node.png, workflow.xml
>
>
> When a job's workflow.xml contains dangling nodes, Oozie doesn't show any
> warning when running the job. For instance, in the following workflow:
> Start -> ForkNode
> ForkNode -> (MR-1, MR-2, MR-2)
> MR-1 -> JoinNode
> MR-2 -> JoinNode
> MR-3 -> JoinNode
> JoinNode -> End
> (notice the intentional error on the right hand side of ForkNode where MR-3
> was replaced by MR-2)
> Oozie ignores the dangling node and runs the job as if it was an error-free
> job, but the job will never succeed since JoinNode keeps waiting for the
> unreachable MR-3 job to succeed.
> Please see attached file for more details.
