> Key: DRILL-7341
> URL: https://issues.apache.org/jira/browse/DRILL-7341
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.16.0
> Reporter: Oleg Zinoviev
> Priority: Major
> Attachments: stacktrace.log
>
>
> There are several methods that modify the BaseDataValueVector#data field.
> Some of them, such as BaseDataValueVector#exchange, do not change
> allocationSizeInBytes.
> Therefore, if BaseDataValueVector#exchange was executed for vectors with
> different size, *ValueVector#reAlloc may create a buffer of insufficient size.
