Hi, I have an RDD containing Vehicle Number , timestamp, Position. I want to get the "lag" function equivalent to my RDD to be able to create track segment of each Vehicle.
Any help? PS: I have tried reduceByKey and then splitting the List of position in tuples. For me it runs out of memory every time because of the volume of data. ...Manas *For some reason I have never got any reply to my emails to the user group. I am hoping to break that trend this time. :)*
