Answer 1

As the input data is not stored as tuple we wont be able to read it directly in to a tuple.

One feasible approach is to read the data and then form a tuple with required fields.

Pig Script :

A = LOAD 'a.csv' USING PigStorage('\t') AS (name:chararray,no:int,result:chararray,school:chararray);
B = FOREACH A GENERATE (name,no) AS T1:tuple(name:chararray, no:int), (result,school) AS T2:tuple(result:chararray, school:chararray);
DUMP B;

Input : a.csv

vineet  1   pass    Govt
hisham  2   pass    Prvt
raj 3   fail    Prvt

Output : DUMP B:

((vineet,1),(pass,Govt))
((hisham,2),(pass,Prvt))
((raj,3),(fail,Prvt))

Output : DESCRIBE B :

B: {T1: (name: chararray,no: int),T2: (result: chararray,school: chararray)}
