---------------------------------
> Use Hive's ORC dependency version when producing file footer for Iceberg
> ------------------------------------------------------------------------
>
> Key: HIVE-26161
> URL: https://issues.apache.org/jira/browse/HIVE-26161
> Project: Hive
> Issue Type: Bug
> Reporter: Ádám Szita
> Assignee: Ádám Szita
> Priority: Major
>
> For schema evolution and projection purposes we produce an ORC file footer
> byte buffer in VectorizedReadUtils.
> Currently Iceberg's bundled/shaded ORC is used to produce these file footer
> bytes when dealing with Iceberg/ORC tables. This version of ORC is newer
> (1.7.3) than what Hive uses (1.6.9).
> Later on we could face compatibility issues when trying to reconstruct an
> OrcTail object with a 1.6.9 reader from the bytes that the 1.7.3 reader
> serialized. We need to invert the direction as we can rely more on backward
> compatibility than on forward compatibility of ORC.
