--------------------------------
Summary: [C++] Properly handle non-nullable fields in Parquet
reading
Key: ARROW-16116
URL: https://issues.apache.org/jira/browse/ARROW-16116
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: David Li
ARROW-15961 found that the Parquet Arrow reader wasn't respecting the nullable
aspect of fields, we need to ensure that if we reconstruct an array for a
non-nullable field, that it has no validity bitmap. We need to also add tests
for this case, they're implicitly tested in a few places, but we should
explicitly test this for all supported types.
