Hi, I'm attempting the TASK 03 on Practice test. PART 1 I was successfully able to load the records into ‘/user/horton/flightdelays_clean’ While attempting the part 2 of TASK 03 I do the following: A = LOAD '/user/horton/flightdelays_clean' USING PigStorage(',') ; --- A has 29534 records B = FILTER A BY $8 == 'DEN'; ---[main] WARN org.apache.pig.newplan.BaseOperatorPlan - ---Encountered Warning IMPLICIT_CAST_TO_CHARARRAY 1 time(s) Output(s): Successfully stored 0 records in: "hdfs://namenode:8020/tmp/temp-577228131/tmp-2029278778" There is no rows being imported into B.

I also tried to import A with Schema like the following: grunt> A = LOAD '/user/horton/flightdelays_clean' USING PigStorage(',') AS (Year:int, Month:int, DayofMonth:int,DepTime:int, UniqueCarrier:chararray, FlightNum:int, ArrDelay:int, Origin:chararray, Dest:chararray); 2016-06-23 18:26:32,428 [main] WARN org.apache.pig.newplan.BaseOperatorPlan - Encountered Warning IMPLICIT_CAST_TO_CHARARRAY 1 time(s). B = FILTER A BY Dest == 'DEN'; I still end up wiht no rows being written to B; I'm not facing errors but I see the string comparision is not working. How can i fix this? @rich ... View more
