                 Key: PIG-256
                 URL: https://issues.apache.org/jira/browse/PIG-256
             Project: Pig
          Issue Type: Improvement
            Reporter: Ajay Garg
            Priority: Minor


pig does not support non default constructor with variable number of arguments 
support. In our case we need this because the number of variables that are 
specified by the user are varying. The fix is simple. Pig calls 
getConstr("agr1","arg2",...,"argn") and if it doesn't find it throws a 
noSuchMethodFound exception. In the catch block we just need to add code to 
check if we can wrap the arg1..n in a String[] and check if a constructor can 
be found with this signature getConstr(args[]). This would resolve the variable 
num args issue.
