URL: https://github.com/apache/spark/pull/42693
### What changes were proposed in this pull request?
This PR fixes the bug in createDataFrame with Python Spark Connect client.
Now it respects inherited namedtuples as below:
```python
from collections import namedtuple
MyTuple = namedtuple("MyTuple", ["zz", "b", "a"])
class MyInheritedTuple(MyTuple):
pass
df = spark.createDataFrame([MyInheritedTuple(1, 2, 3), MyInheritedTuple(11,
22, 33)])
df.collect()
```
Before:
```
[Row(zz=None, b=None, a=None), Row(zz=None, b=None, a=None)]
```
After:
```
[Row(zz=1, b=2, a=3), Row(zz=11, b=22, a=33)]
```
### Why are the changes needed?
This is already supported without Spark Connect. We should match the
behaviour for consistent API support.
### Does this PR introduce _any_ user-facing change?
Yes, as described above. It fixes a bug,
### How was this patch tested?
Manually tested as described above, and unittests were added.
### Was this patch authored or co-authored using generative AI tooling?
No.
