Hi, I have a dataset of time as shown below : Time1 07:30:23 07:34:34 07:38:23 07:39:12 07:45:20
I need to find the diff between two consecutive rows I googled and found the *lag *function in *spark *helps in finding it . but its not giving me *null *in the result set. Would really appreciate the help. Thanks, Divya
