Joshua Howard updated PARQUET-2088: ----------------------------------- Description: There seems to be a discrepancy in the Parquet format created_by field regarding how it should be filled out. The parquet-mr library uses this value to enable/disable features based on the parquet-mr version [here|https://github.com/apache/parquet-mr/blob/5f403501e9de05b6aa48f028191b4e78bb97fb12/parquet-column/src/main/java/org/apache/parquet/CorruptDeltaByteArrays.java#L64-L68]. Meanwhile, users are encouraged to make use of the application version [here|https://www.javadoc.io/doc/org.apache.parquet/parquet-format/latest/org/apache/parquet/format/FileMetaData.html]. It seems like there are multiple fields needed for an application and library version.
