org.apache.pig.builtin.TRIM
Returns a string, with leading and trailing whitespace omitted. Implements a binding to the Java function {@link java.lang.String#trim() String.trim()}.

        input = TupleFactory.getInstance().newTuple(l);
        expected = "ello";
        output = strFunc.exec(input);
        assertTrue(output.equals(expected));


        strFunc = new TRIM();
        input = TupleFactory.getInstance().newTuple(inpuStrExtra);
        expected = inputStr;
        output = strFunc.exec(input);
        assertTrue(output.equals(expected));
