DIFF contains an invalid expression - possible parser error
-----------------------------------------------------------
Key: PIG-670
URL: https://issues.apache.org/jira/browse/PIG-670
Project: Pig
Issue Type: Bug
Environment: i686 i386 GNU/Linux
Reporter: Araceli Henley
Requires further investigation.
This test takes in an invalid expression as the first argument in the DIFF
function and results in the following error:
ERROR 1000: Error during parsing. Invalid alias: DIFF
Why is the parser interpreting DIFF as an alias?
TEST: AggregateFunc_131
A =LOAD '/user/pig/tests/data/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 DIFF( A.Fint + A.Fint + );
STORE X INTO '/user/pig/tests/results/araceli.1234381533/AggregateFunc_131.out'
USING PigStorage();
