> Project: Spark
> Issue Type: Test

> Affects Versions: 3.4.0
> Reporter: Haejoon Lee

> There is inconsistent behavior on `Index.intersection` when `other` is list
> of tuple for pandas API on Spark as below:
> {code:python}
> >>> pidx
> Int64Index([1, 2, 3, 4], dtype='int64', name='Koalas')
> >>> psidx
> Int64Index([1, 2, 3, 4], dtype='int64', name='Koalas')
> >>> psidx.intersection([(1, 2), (3, 4)]).sort_values()
> MultiIndex([], )
> >>> pidx.intersection([(1, 2), (3, 4)]).sort_values()
> Traceback (most recent call last):
> ...
> ValueError: Names should be list-like for a MultiIndex
> {code}
> We should fix it to follow pandas.
