> While working on [PR #31490|https://github.com/apache/spark/pull/31490] for SPARK-34365, we discussed that there is room for improvement in how schema mismatch errors are reported ([comment1|https://github.com/apache/spark/pull/31490#discussion_r659970793], [comment2|https://github.com/apache/spark/pull/31490#issuecomment-869866848]). We can also consolidate more of the logic between AvroSerializer and AvroDeserializer to avoid some duplication of error handling and consolidate how these error messages are generated.
> This will essentially be taking the [logic from the initial proposal from PR #31490|https://github.com/apache/spark/pull/31490/commits/83a922fdff08528e59233f67930ac78bfb3fa178], but applied separately from the current set of proposed changes to cut down on PR size.
