And please try to switch the left and right side of the join and see if the result changes.
JoinQuery.SpatialJoingQueryFlat(RddA, RddB, considerBoundaryIntersection) means that check if each one in Rdd A is CONTAINED BY each one in Rdd B, considering the situation of boundary intersecting (not fully contained). In your case, a line cannot contain a polygon, but a polygon can contain a line. Make sure you get the order correct.
