Input: Ticket#|Date of booking|Price 100|20-Oct-13|54 100|21-Oct-13|56 100|22-Oct-13|54 100|23-Oct-13|55 100|27-Oct-13|60 100|30-Oct-13|47 101|10-Sep-13|12 101|13-Sep-13|14 101|20-Oct-13|6 Expected Output: Ticket#|Initial|Delta1|Delta2|Delta3|Delta4|Delta5 100|20-Oct-13,54|21-Oct-13,2|22-Oct-13,0|23-Oct-3,1|27-Oct-13,6|30-Oct-13,-7 101|10-Sep-13,12|13-Sep-13,2|20-Oct-13,-6||| The number of columns in the expected output is a dynamic list depending on the number of price changes of a ticket. 1) What is the best design to solve the above problem in Hive? 2) How do we implement it? Please advise. Regards, Raj
