Question:

Q 1. Assume we use datafu lib in pig:
DEFINE EmptyBagToNullFields datafu.pig.bags.EmptyBagToNullFields();
data = FOREACH (COGROUP input1 BY key, input2 BY key, input3 BY key) GENERATE
FLATTEN(input1),
FLATTEN(EmptyBagToNullFields(input2)),
FLATTEN(EmptyBagToNullFields(input3));
Which script will define macro similar to above script?

DEFINE myFunction(relation1, key1, relation2, key2, relation3, key3) returns result {
A = GROUP $relation1 BY $key1, $relation2 BY $key2, $relation3 BY $key3;
$result = FOREACH A GENERATE
FLATTEN($relation1),
FLATTEN(EmptyBagToNullFields($relation2)),
FLATTEN(EmptyBagToNullFields($relation3));
}

DEFINE myFunction(relation1, key1, relation2, key2, relation3, key3) returns result {
A = JOIN $relation1 BY $key1, $relation2 BY $key2, $relation3 BY $key3;
$result = FOREACH A GENERATE
FLATTEN($relation1),
FLATTEN(EmptyBagToNullFields($relation2)),
FLATTEN(EmptyBagToNullFields($relation3));
}

Cannot replace to have same logic with above script

DEFINE myFunction(relation1, key1, relation2, key2, relation3, key3) returns result {
A = COGROUP $relation1 BY $key1, $relation2 BY $key2, $relation3 BY $key3;
$result = FOREACH A GENERATE
FLATTEN($relation1),
FLATTEN(EmptyBagToNullFields($relation2)),
FLATTEN(EmptyBagToNullFields($relation3));
}
