> As described [here|https://issues.apache.org/jira/browse/OOZIE-1035?focusedCommentId=13676534&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13676534] in OOZIE-1035, the new forkjoin checker code is blocking some valid cases involving decision nodes where the decision nodes are inside the forkjoin; when they are outside, its not a problem.
> 1) This uses a decision node to "insert" an action based on {{foo}}:
> {noformat}
> <fork>
>    <goto decision>
>    <goto join>
> </fork>
> <decision>
>    <if foo, goto A>
>    <else, goto B>
> </decision>
> <action A>
>    <ok to="B">
> </action A>
> <action B>
>    <ok to="join">
> </action B>
> <join>
> {noformat}
> 2) This uses a decision node to "replace" an action based on {{foo}}:
> {noformat}
> <fork>
>    <goto decision>
>    <goto join>
> </fork>
> <decision>
>    <if foo, goto A>
>    <else, goto B>
> </decision>
> <action A>
>    <ok to="join">
> </action A>
> <action B>
>    <ok to="join">
> </action B>
> <join>
> {noformat}
