Docs generation has been working great recently.

>                 URL: https://issues.apache.org/jira/browse/OOZIE-1022
>             Project: Oozie
>          Issue Type: Improvement
>          Components: docs
>    Affects Versions: trunk
>            Reporter: Robert Kanter
>            Priority: Minor
>
> When you tell maven to generate the docs, it takes a while and then eventually prints this:
> {code}
> [ERROR] Java heap space -> [Help 1]
> [ERROR] 
> [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
> [ERROR] Re-run Maven using the -X switch to enable full debug logging.
> [ERROR] 
> [ERROR] For more information about the errors and possible solutions, please read the following articles:
> [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/OutOfMemoryError
> {code}
> If I do {{export MAVEN_OPTS="-Xmx1024m}} and then run maven, it works (though very slowly; a higher number might be faster).  
> We should give maven more heap space when generating the docs; I assume there's some config property in a pom or something for this.  
> Alternatively, maybe we're doing something wrong?  We don't have _that_ many doc pages that it should require so much heap space.
