> Key: IMPALA-2230
> URL: https://issues.apache.org/jira/browse/IMPALA-2230
> Project: IMPALA
> Issue Type: Task
> Components: Backend
> Affects Versions: Impala 2.2.4
> Reporter: Skye Wanderman-Milne
> Priority: Minor
>
> We have a lot of untested error handling in the Parquet scanner. It would be
> good to hand-craft test files that exercise some of these cases, including:
> (feel free to edit to add more cases)
> * Columns with different numbers of values
> * Columns with mismatched # values vs # values reported in metadata
