Haejoon Lee updated SPARK-40265:
--------------------------------
Description:
There is inconsistent behavior on Index.intersection for pandas API on Spark as
below:
{code:python}
>>> other = [(1, 2), (3, 4)]
>>> pidx
Int64Index([1, 2, 3, 4], dtype='int64', name='Koalas')
>>> psidx
Int64Index([1, 2, 3, 4], dtype='int64', name='Koalas')
>>> psidx.intersection(other).sort_values()
MultiIndex([], )
>>> pidx.intersection(other).sort_values()
Traceback (most recent call last):
...
ValueError: Names should be list-like for a MultiIndex
{code}
We should fix it to follow pandas.
