It is certainly possible through a hack.I was referring to below post where TD says it is possible thru a hack. I wanted to know if there is any way other than editing the Spark source code.--On Wed, Mar 1, 2017 at 7:09 AM, Saisai Shao <firstname.lastname@example.org> wrote:I don't think using ManualClock is a right way to fix your problem here in Spark Streaming.ManualClock in Spark is mainly used for unit test, it should manually advance the time to make the unit test work. The usage looks different compared to the scenario you mentioned.Thanks

I have a usecase where all incoming events have a fixed latency of 10s, which means data belonging to minute 10:00:00 will arrive 10s late at 10:00:10.I want to set the spark clock to "Manualclock" and set the time behind by 10s so that the batch calculation triggers at 10:00:10, during which time all the events for the previous minute has arrived.But, I see thatIs there a way to easily hack this property to use Manual clock.--
