Description

arr = np.array([date(2017, 4, 3), date(2017, 4, 4)], dtype='datetime64[D]')
mask = [True, False]
t32 = pa.date32()
result = pa.array(arr, mask=np.array(mask))
expected = pa.array(np.array([None, date(2017, 4, 4)], dtype='datetime64[D]'))

The above code produces an array that has no null values.
