--------------------------------------
Fix Version/s: 2.2.1
> Reallocation in OffHeapColumnVector.reserveInternal corrupts array data
> -----------------------------------------------------------------------
>
> Key: SPARK-22092
> URL: https://issues.apache.org/jira/browse/SPARK-22092
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Ala Luszczak
> Assignee: Ala Luszczak
> Fix For: 2.2.1, 2.3.0
>
>
> OffHeapColumnVector.reserveInternal() will only copy already inserted values
> during reallocation if this.data != null. However, for vectors containing
> arrays, field data is disused and always equals null. Hence, the reallocation
> of array vector always causes data loss.
