Micah Kornfield commented on ARROW-8228:
----------------------------------------
The case that isn't covered is if you have something like:
Null bitmap: [Not Null, Null, Not Null]
List_offset = [0, 2, 5, 7]
Data= [0, 1, 2, 3, 4, 5, 6]
Nullable FixedSizeList also runs into this issue (any nulls in the middle can't
be written).
> [C++][Parquet] Support writing lists that have null elements that are
> non-empty.

> With the new V2 level writing engine we can detect this case but fail as not
> implemented. Fixing this will require changes to the "core" parquet API.
