Etienne Chauchot created FLINK-21388:
----------------------------------------
Summary: Parquet DECIMAL logical type is not properly supported in
ParquetInputFormat
Key: FLINK-21388
URL: https://issues.apache.org/jira/browse/FLINK-21388
Project: Flink
Issue Type: Bug
Reporter: Etienne Chauchot
For a parquet field such as this one
{code:java}
optional int32 ss_wholesale_cost (DECIMAL(7,2));{code}
_ParquetSchemaConverter_ raises the exception:
{code:java}
Unsupported original type : DECIMAL for primitive type INT32{code}
whereas it should be mapped to flink _DECIMAL_ Datatype (_BIG_DEC_ type
information) owing to
https://ci.apache.org/projects/flink/flink-docs-stable/dev/table/connectors/formats/parquet.html#data-type-mapping
and
https://ci.apache.org/projects/flink/flink-docs-stable/dev/table/types.html#old-planner
