Hi,
I have this script, how to achive results ?
====================================================================================
A = LOAD 'file:///home/hadoop/1.csv' USING PigStorage(',') AS
(name:chararray, aa:float, bb:float, cc:float, dd:float);
B = FILTER A BY cc > 0;
C = GROUP B BY name;
D = FOREACH C GENERATE group,
SUM(B.cc)/SUM(B.aa)/SUM(B.bb) as allsum;
E= FOREACH B GENERATE cc*dd/allsum;
=====================================================================================
The last one could not work.
Looking forward to experts input. Thanks.
Best Regards,
