Ádám Szita created HIVE-26161: --------------------------------- Summary: 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
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. -- This message was sent by Atlassian Jira (v8.20.7#820007)
