Examples of org.apache.pig.builtin.COUNT_STAR$Initial

org.apache.pig.builtin.COUNT_STAR
Generates the count of the values of the first field of a tuple. This class is different from COUNT in that it counts all NULL values and as such implements SQL COUNT(*) semantics. This class is Algebraic in implemenation, so if possible the execution will be split into a local and global functions

    @Test
    public void testCOUNT_STAR() throws Exception {
        Integer input[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, null };
        long expected = input.length;


        EvalFunc<Long> count = new COUNT_STAR();
        Tuple tup = Util.loadNestTuple(TupleFactory.getInstance().newTuple(1), input);
        Long output = count.exec(tup);


        assertTrue(output == expected);
