https://github.com/apache/spark/pull/22353
> Abbreviated metadata in DataSourceScanExec results in incomplete information
> in event log
> -----------------------------------------------------------------------------------------
>
> Key: SPARK-25357
> URL: https://issues.apache.org/jira/browse/SPARK-25357
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.1
> Reporter: Lantao Jin
> Priority: Minor
>
> Field {{metadata}} removed from {{SparkPlanInfo}} in SPARK-17701.
> Corresponding, this field was also removed from event
> {{SparkListenerSQLExecutionStart}} in Spark event log. If we want to analyze
> event log to get some fields which wider than 100 (e.g the Location or
> ReadSchema of FileScan), they are abbreviated in {{simpleString}} of
> SparkPlanInfo JSON or {{physicalPlanDescription}} JSON.
> Before 2.3, the fragment of SparkListenerSQLExecutionStart in event log (It
> contains the metadata field):
