Hi. I stumbled on weird behaviour (bug?) when joining PTable<?, Void> on left side with any other PTable - resulting collection is empty. Attached example code demonstrates unexpected behaviour. Code in question is in org.apache.crunch.lib.join.InnerJoinFn line 59 where it checks for null reference on left dataset (same for other join fn implementations). Anyone can comment on this?
