> TimeJoinOperator should wait for all children have data, then it can do the
> calculation. However, currently in its isBlocked() method, we only return one
> child's block state. If this child's block state is unblocked. Then
> TimeJoinOperator will do its calculation which is incorrect because other
> children may be in block state.
