-----------------------------------------
Summary: ValidateFull() does not validate null_count
Key: ARROW-10373
URL: https://issues.apache.org/jira/browse/ARROW-10373
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Derek Denny-Brown
Attachments: arrow_null_count.cpp
It is possible to corrupt a serialized record batch such that the null_count of
the parsed result is invalid. Attached is a repro where the the parsed
null_count = -2, but ValidateFull returns success. I would expect ValidateFull
to verify the null_count against the serialized columns.
