Hi all,
I got a hint via StackOverflow[1] the problem was the missing
delimiter definition

this should read
data1 = load 'data1' using PigStorage(',') as (key: chararray, val: chararray);
data2 = load 'data2' using PigStorage(',') as (key: chararray, val: chararray);
assoc = load 'assoc' using PigStorage(',') as (key1: chararray, key2:
chararray);
I got confused because the original statement yielded
grunt> dump data1;
(key1,foo,)
(key2,bar,)
So I took for granted that this is a tuple…
Sorry for the noise,
Thomas Bach.
