Hi,
I have the following requirement from a Hive table below. CustNumActivityDatesRates 10010-Aug-13,12-Aug-13,20-Aug-1310,15,20 The data above says that From 10 Aug to 11 Aug the rate is 10. From 12 Aug to 19 Aug the rate is 15. From 20-Aug to till date the rate is 20. Note : The order is maintained in 'ActivityDates' and 'Rates'. From the above table , I need to find the rate on say a given date 15-Aug-13. In the above case , the rate for 15-Aug-13 is 15. How should I get this result in Hive. I was reading about a Generic UDF and was thinking to write one like this. The Generic UDF takes two inputs (input date , array of input dates ) . the output should be (an int )to return the element number in the array. In the above case Generic UDF(15-Aug-13,10-Aug-13,12-Aug-13,20-Aug-13) should return the 2nd element in array - 2. Please advise if there is an alternative solution or if the above solution works. I have never written a UDF or Generic UDF and would need some help from the forum members. Please advise. Regards, Raj
