[jira] [Comment Edited] (SPARK-34785) SPARK-34212 issue not fixed
if spark.sql.parquet.enableVectorizedReader=true which is default value.
Error Parquet column cannot be converted in file.

-----------------------------------------------------------------
FYI, each data sources have different schema evolution capabilities. And, Parquet is not the best built-in data source in terms of it. We are tracking it with the following test suite.
- https://github.com/apache/spark/blob/master/sql/core/src/test/scala/org/apache/spark/sql/execution/datasources/ReadSchemaTest.scala
The recommendation is to use MR code path if you are in that situation.
