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));
}

Q 2. A = load 'Data1' as (name:chararray, team:chararray, position:bag{t:(p:chararray)}, bat:map[]);
B = foreach A generate name, team, position, bat#'batting_average' as batavg;
C = group B by team;
avgC = foreach C generate group, AVG(B.batavg);
store avgC into 'by_team';
flattenData = foreach B generate name, team, flatten(position) as position, batavg;
D = group flattenData by position parallel 100;
avgD = foreach D generate group, AVG(flattenData.batavg);
store avgD into 'Rank';

How many reduce will run at D relation?

100

Not enough information

Depend on Data1 file
