Hi Stuart! We are still waiting for Hadoop 0.20 to be released and after we have that maybe 2 weeks or so to finalize our release and get most of the bugs fixed, not really sure how they are doing over at Hadoop, but I would guess 4-6 weeks or so. Hopefully we will have a functioning trunk in not to long with most of the 0.20 features functioning, but there are still some open issues for 0.20, have a look at https://issues.apache.org/jira/secure/IssueNavigator.jspa?mode=hide&requestId=12313132
Regards Erik
