### Apache Iceberg version 1.6.1 (latest release) ### Query engine Spark ### Please describe the bug 🐞 Problem: Executing "system.add_files(... parallelism => 2)" results in a NotSerializableException for an instance ExecutorService: Task not serializable: java.io.NotSerializableException: java.util.concurrent.Executors$Delegated**ExecutorService** in MapPartitionsRDD[16] at collectAsList at **SparkTableUtil.java:792**, org.apache.spark.ShuffleDependency@12d6880f Expectations: add_files runs without exception, also if parallelism > 1. Suggestions: Dont pass ExecutorService instance from the Spark driver as argument to listPartition in SparkTableUtils.java:759, but create ExecutorService in listPartitions on the Spark executor. ### Willingness to contribute - [ ] I can contribute a fix for this bug independently - [ ] I would be willing to contribute a fix for this bug with guidance from the Iceberg community - [ ] I cannot contribute a fix for this bug at this time -- This is an automated message from the Apache Git Service.
