-------------------------------------------
Hello, [~zi]
I've tried this approach:
import org.apache.spark.\{SPARK_VERSION}
override def getName: String = {
SPARK_VERSION
}
Spark is building with this code. Also I have an idea to add configuration to
SQLConf which was already imported to ParquetWriteSupport.
Code will look something like this, below is config added to SQLConf:
val SPARK_VERSION = buildConf("spark.sql.writerModelName")
.doc("Version of Spark which create Parquet file")
.stringConf
.createWithDefault(SparkContext.getOrCreate().version)
And method getName:
override def getName: String = {
SQLConf.SPARK_VERSION.key
}
I've created pull request with the first variant. Which one is better (if any
of them is valid at all)?

> URL: https://issues.apache.org/jira/browse/SPARK-25102
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.3.1
> Reporter: Zoltan Ivanfi
> Priority: Major
>
> -PARQUET-352- added support for the "writer.model.name" property in the
> Parquet metadata to identify the object model (application) that wrote the
> file.
> The easiest way to write this property is by overriding getName() of
> org.apache.parquet.hadoop.api.WriteSupport. In Spark, this would mean adding
> getName() to the
> org.apache.spark.sql.execution.datasources.parquet.ParquetWriteSupport class.
