Review comment:
       I was also able to test successfully loading segment files from S3 as 
deep storage. But did not test with any S3 encryption protocols yet. Here is a 
code snippet..
   
   `
   import java.util.UUID

StructType}

     private val localSparkContext = new ThreadLocal[SparkContext]
     private val localSparkSession = new ThreadLocal[SparkSession]
     private val MAPPER = new DefaultObjectMapper()
   
   
     def sparkSession: SparkSession = localSparkSession.get()
   
   
     val dataSource: String = "......."
   
     private def setupSparkContextAndSession(): Unit = {
   
   
       val sparkConf = new SparkConf(loadDefaults = true)
       sparkConf.setAppName(UUID.randomUUID.toString).setMaster("local")
   
   
       localSparkContext.set(new SparkContext(sparkConf))
       localSparkContext.get().hadoopConfiguration.set("fs.s3n.awsAccessKeyId",

         .format("org.apache.druid.spark.v2.DruidDataSourceV2")
