-------------------------------------
Summary: Spark SQL's native ORC reader implements its own schema
evolution
Key: SPARK-27913
URL: https://issues.apache.org/jira/browse/SPARK-27913
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.3.3
Reporter: Owen O'Malley
ORC's reader handles a wide range of schema evolution, but the Spark SQL native
ORC bindings do not provide the desired schema to the ORC reader. This causes a
regression when moving spark.sql.orc.impl from 'hive' to 'native'.
