Hi, [~zi]. I've tried to override getName method in
org.apache.spark.sql.execution.datasources.parquet.ParquetWriteSupport. The
problem is that the only way (that i know about) to find Spark version
programmatically on an executor node is
SparkSession.builder().getOrCreate().version. But, when I ran tests i received
the following error:
Caused by: java.lang.IllegalStateException: SparkSession should only be
created and accessed on the driver.
Do you know any other way to find Spark version in an executor?

> Write Spark version information to Parquet file footers

> Key: SPARK-25102
> 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.
