Trivial Description
The Javadoc for PTable#cogroup maybe confusing when comparing it to the PTable#join javadoc
/** * Perform an inner join on this table and the one passed in as an argument on * their common keys. */ <U> PTable<K, Pair<V, U>> join(PTable<K, U> other); /** * Co-group operation with the given table on common keys. */ <U> PTable<K, Pair<Collection<V>, Collection<U>>> cogroup(PTable<K, U> other);
The phrasing of "common keys" in the cogroup method make it sound like the cogroup will be a inner join on the table. I think removing the "common keys" from the cogroup method will remove that confusion.
