>                 URL: https://issues.apache.org/jira/browse/OOZIE-569

>          Issue Type: Bug
>            Reporter: Parameswaran Raman
>
> In the documentation for 'external dataset definition' - 
> http://yahoo.github.com/oozie/releases/3.0.2/CoordinatorFunctionalSpec.html, 
> it needs to be mentioned that:
> If a xml namespace (xmlns="xyz") is already present for <coordinator-app> 
> then there is no need to specify it again on any of the <datasets> or 
> <dataset> elements (even if the dataset is defined in a separate xml file).
> Specifying namespaces at multiple places, results in xml errors while 
> submitting the job.
> CORRECT SPECIFICATION:
> ------------------------------------------
> <coordinator-app name="aggreg"  xmlns="uri:oozie:coordinator:0.2">
>      .....
>    <datasets>
>        <dataset>
>        ..
>        </dataset>
>      .....
>    </datasets>
>      .....
> </coordinator-app>
> INCORRECT SPECIFICATION:
> ------------------------------------------
> <coordinator-app name="aggreg"  xmlns="uri:oozie:coordinator:0.2">
>      .....
>    <datasets xmlns="uri:oozie:coordinator:0.2">
>        <include>
>        ..
>        </include>
>        <dataset>
>        ..
>        </dataset>
>      .....
>    </datasets>
>      .....
> </coordinator-app>
