------------------------------------------------------
Key: PIG-676
URL: https://issues.apache.org/jira/browse/PIG-676
Project: Pig
Issue Type: Bug
Environment: i686 i386 GNU/Linux
ava version "1.6.0_02"
Java(TM) SE Runtime Environment (build 1.6.0_02-b05)
Java HotSpot(TM) Client VM (build 1.6.0_02-b05, mixed mode, sharing)
Reporter: Araceli Henley
Priority: Trivial
I passed in a constant value "0.0" for the first argument, aexpecting that an
error such as "Invalid type passed to DIFF" or some such error, but this is
processed without any errors.
TEST: AggregateFunc_101
A =LOAD ':INPATH:/types/DataAll' USING PigStorage() AS ( Fint:int, Flong:long,
Fdouble:double, Ffloat:float, Fchar:chararray, Fchararray:chararray,
Fbytearray:bytearray, Fmap:map[], Fbag:BAG{ t:tuple( name, age, avg ) },
Ftuple:( name:chararray, age:int, avg:float) );
B =GROUP A ALL;
X =FOREACH B GENERATE A.Fint, DIFF( 0.0, A.Fbag );
STORE X INTO ':OUTPATH:' USING PigStorage();
