> Hi,
> I would like to add a new strategy to {{SQLContext}}. To do this I created a new class which extends {{Strategy}}. In my new class I need to call {{planLater}} function. However this method is defined in {{SparkPlanner}} (which itself inherits the method from {{QueryPlanner}}).
> To my knowledge the only way to make {{planLater}} function visible to my new strategy is to define my strategy inside another class that extends {{SparkPlanner}} and inherits {{planLater}} as a result, by doing so I will have to extend the {{SQLContext}} such that I can override the {{planner}} field with the new {{Planner}} class I created.
> It seems that this is a design problem because adding a new strategy seems to require extending {{SQLContext}} (unless I am doing it wrong and there is a better way to do it).
> Thanks a lot,
> Youssef
