我试着用这两种方法安装spark\u avro包
第1种方法

spark-submit --packages org.apache.spark:spark-avro:3.0.2 ...

第二种方法

spark-submit --jars spark-avro_2.12-3.0.2.jar ...

对于第二种方法，我下载了所需的jar并将其放在spark所在的文件夹中，然后运行。
两种方法都显示相同的异常：

C:\spark\spark\bin>spark-submit --packages org.apache.spark:spark-avro_2.12:3.0.2 ...
C:\spark\spark\bin>spark-submit --jars spark-avro_2.12-3.0.2.jar ...

这两个都给出了如下相同的错误，

Exception in thread "main" org.apache.spark.SparkException: Failed to get main class in JAR with error 'C:\spark\spark\bin\... (Access is denied)'.  Please specify one with --class.
