How to convert target values with pig?

Question

I have some data with a target of 4 values ​​and I want three of these to become part of one single using latin pig.

Input:                     Output:
ID     | Target            ID     | Target    
-----------------          -----------------
test1      1               test1      1
test2      1               test2      1
test3      2               test3      2
test4      2               test4      2
test5      3               test5      2
test6      4               test6      2
test7      2               test7      2

Someone knows the best way to do it

Answer 1

Use Bincond to check for target value greater than 1 and if true replace it with the value you want,in this case 2.

A = LOAD 'data.txt' USING PigStorage('\t') AS (Id:chararray,target:int);
B = FOREACH A GENERATE Id,(target > 1 ? 2 : target);
DUMP B;
