我已经创建了一个pyspark代码并从oozie运行该作业。这个.py文件需要一个spark-solr阴影jar所以我下载了一个带阴影的jar，我指的是这个jar使用--jars在oozie中的spark-opts。 当我从命令行运行yarn时，此代码工作正常，但是当我从oozie作业运行此代码时，它会给我以下错误。我已经看到其他类似错误的问题，人们创建一个阴影jar并需要添加清单文件，但我没有创建任何jar文件，我只是使用一个阴影jar，如果不是oozie就可以正常工作。

如何解决此错误？
答案 0 :(得分：0)
看起来hive在找到它的罐子和/或XML文件时遇到了问题。
尝试添加这些罐子：
蜂房common.jar
datanucleus-core-3.2.10.jar（此版本不需要）
datanucleus-rdbms-3.2.9.jar（此版本不需要）
还要确保在运行spark
时加载了hive-site.xml
