I propose we remove Penny from contrib. Currently it does not compile in trunk. Looking through the commit logs no significant work has been done on it since it was initially committed. There are 3 open JIRAs that reference it ( https://issues.apache.org/jira/secure/IssueNavigator.jspa?reset=true&jqlQuery=project+%3D+PIG+AND+%28summary+%7E+penny+OR+description+%7E+penny%29+AND+status+%3D+Open ). At this point I do not think anyone is using it or maintaining it.
If someone is interested in moving this piece forward I would propose we move it to Apache Extras or something similar. Alan.
