我使用spark submit运行scala jar，它引发了一个错误：
线程“main”org.apache.spark.sql.analysisexception中出现异常：找不到数据源：avro。avro是内置的，但外部数据源模块，因为Spark2.4。请按照“ApacheAvro数据源指南”的部署部分部署应用程序。；
依赖关系是

<groupId>org.apache.spark</groupId>
    <artifactId>spark-avro_2.11</artifactId>
<version>2.4.4</version>

似乎avro依赖项不起作用。
但如果我加上——包org.apache。spark:spark-avro_2.11：2.4.4在spark submit命令中，它可以工作。
