我想用oozie来称呼spark jobs。使用spark submit，spark作业可以在没有oozie的情况下成功运行：

spark-submit --class xxx --master yarn-cluster --files xxx/hive-site.xml --jars xxx/datanucleus-api-jdo-3.2.6.jar,xxx/datanucleus-rdbms-3.2.9.jar,xxx/datanucleus-core-3.2.10.jar xxx.jar

但是当我尝试使用oozie调用作业时，它总是会失败，并出现以下错误。我在workflow.xml中包含了3个外部jar和hive-site.xml

Launcher exception: org/apache/spark/sql/hive/HiveContext

我的scala代码的第20行是：

val sqlContext = new org.apache.spark.sql.hive.HiveContext(sc)

有人知道这个错误吗？我被困了好几天了。
谢谢您！
