[jira] [Commented] (SPARK-25102) Write Spark version information to
Parquet file footers
[ https://issues.apache.org/jira/browse/SPARK-25102?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16609062#comment-16609062 ]

Hi [~npoberezkin],
Sorry for answering so late, I was on vacation. Unfortunately I can't tell you what the proper way is to get the Spark version as I am not a Spark developer myself but a Parquet library developer instead.
> 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.
