Summary: Allow reading Parquet TimestampLTZ as TimestampNTZ
Key: SPARK-47447
URL: https://issues.apache.org/jira/browse/SPARK-47447
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 4.0.0
Reporter: Gengliang Wang
Assignee: Gengliang Wang
Currently, Parquet TimestampNTZ type columns can be read as TimestampLTZ, while
reading TimestampLTZ as TimestampNTZ will cause errors. This makes it
impossible to read parquet files containing both TimestampLTZ and TimestampNTZ
as TimestampNTZ.
To make the data type system on Parquet simpler, we should allow reading
TimestampLTZ as TimestampNTZ in the Parquet data source.
