use spark-3.3.2-bin-hadoop3.tgz and do not use spark-3.3.2-bin-hadoop3-scala2.13.tgz

spark-3.3.2-bin-hadoop3.tgz 和 spark-3.3.2-bin-hadoop3-scala2.13.tgz 区别

spark-3.3.2-bin-hadoop3.tgz 和 spark-3.3.2-bin-hadoop3-scala2.13.tgz 都是 Apache Spark 的二进制发布包，它们的区别在于 Scala 的版本。

spark-3.3.2-bin-hadoop3.tgz：该版本的 Spark 使用的是 Scala 2.12.x 版本编译的，适用于 Hadoop 3.x 版本的集群。

spark-3.3.2-bin-hadoop3-scala2.13.tgz：该版本的 Spark 使用的是 Scala 2.13.x 版本编译的，同样适用于 Hadoop 3.x 版本的集群。这个版本的 Spark 适用于使用 Scala 2.13.x 作为主要编程语言的项目。

因此，如果你的项目使用的是 Scala 2.12.x，那么你应该选择 spark-3.3.2-bin-hadoop3.tgz 版本的 Spark。如果你的项目使用的是 Scala 2.13.x，那么你应该选择 spark-3.3.2-bin-hadoop3-scala2.13.tgz 版本的 Spark。
