Question

我创建了自己的SPARK连接器（在Mule ESB中）

不幸的是，我收到错误消息：

 `Exception stack is:
Could not initialize class org.apache.spark.rdd.RDDOperationScope$ (java.lang.NoClassDefFoundError). (org.mule.api.MessagingException)

`

我使用：

m子esb-3.9
spark-core_2.11-2.3.1
spark-sql_2.11-2.3.1

您知道什么地方可能出问题吗？

无法初始化类org.apache.spark.rdd.RDDOperationScope-Mule ESB
