After repartition(), calling first() gives the wrong record. Probably the RDD need to be sorted.

data = td.images.fromarray(np.ones(shape=( 100, 2, 2)),engine=sc, npartitions=10)
def func(kv):
    k, v = kv
    v = k*v
    return v
data = data.map(func, with_keys=True)
data.first()
out: array([[ 1.,  1.],
       [ 1.,  1.]])
data = data.repartition(25)
data.first()
out: array([[ 20.,  20.],
       [ 20.,  20.]])
