             Summary: Parquet INT64 (TIMESTAMP(NANOS,true)) now throwing Illegal Parquet type instead of automatically converting to LongType 
                 Key: SPARK-40819
                 URL: https://issues.apache.org/jira/browse/SPARK-40819
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.2.2, 3.3.0, 3.2.1, 3.2.0
            Reporter: Alfred Davidson


Since 3.2 parquet files containing attributes with type "INT64 (TIMESTAMP(NANOS, true))" are no longer readable and attempting to read throws:

Prior to 3.2 successfully reads the parquet automatically converting to a LongType.

I believe work part of https://issues.apache.org/jira/browse/SPARK-34661 introduced the change in behaviour, more specifically here: [https://github.com/apache/spark/pull/31776/files#diff-3730a913c4b95edf09fb78f8739c538bae53f7269555b6226efe7ccee1901b39R154] which throws the QueryCompilationErrors.illegalParquetTypeError
