… option plumbing Add WRITER_VERSION and OUTPUT_TIMESTAMP_TYPE options to ParquetOptions so callers (e.g., Delta Lake) can control the Parquet writer version and timestamp encoding through the write options map. Wire both through ParquetUtils.prepareWrite() to the Hadoop Configuration. Co-authored-by: Isaac

This PR adds
parquet.writer.versionandspark.sql.parquet.outputTimestampTypetoParquetOptionsand allows them to be plumbed down to Parquet writes via this mechanism. Note thatparquet.writer.versionis named differently than other configs (nosparkprefix) because it is defined in theparquet-javadependency and passed down directly via Spark. These configs are already settable via SQL confs (see existing test case) and are just dropped when passed via writer options (df.option("foo", "bar").save()), so this PR is just fixing that.Why are the changes needed?
These changes are required to open source the functionality to configure the Parquet format version for writes to Delta and Iceberg tables.
Does this PR introduce any user-facing change?
No
How was this patch tested?
Integration tests to validate that these configurations can be pushed down via writer options.
