java - 在Apache Spark上运行JPMML时出现UnmarshalException

Question

我正在尝试在Apache Spark 2.0.1上运行使用JPPML版本1.4.1的代码。 pom文件的相关部分如下:

....

<dependency>
      <groupId>org.apache.spark</groupId>
      <artifactId>spark-core_2.11</artifactId>
      <version>2.0.1</version>
</dependency>

....

<dependency>
    <groupId>org.jpmml</groupId>
    <artifactId>pmml-evaluator</artifactId>
    <version>1.4.1</version>
</dependency>
<dependency>
    <groupId>org.jpmml</groupId>
    <artifactId>pmml-evaluator-extension</artifactId>
    <version>1.4.1</version>
</dependency>
<dependency>
    <groupId>org.jpmml</groupId>
    <artifactId>pmml-model</artifactId>
    <version>1.4.1</version>
</dependency>

但是，我得到UnmarshalException:

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.dmg.org/PMML-4_3", local:"PMML").

现在，JPMML-SparkML依赖于JPMML-Model库的最新和最大版本，该版本与Apache Spark发行版中的旧版冲突。该冲突记录在SPARK-15526中。

我尝试着色并删除了pmml-schema-1.2.15.jar和pmml-model-1.2.15.jar文件，但没有任何效果。

如何解决？

Answer 1

实际上，我通过删除Spark的jars文件夹中的pmml-schema-1.2.15.jar和pmml-model-1.2.15.jar来解决此问题。它不起作用的原因是因为我删除了群集中Spark文件夹中的文件，但没有删除本地Spark文件夹中的文件(需要同时删除这两个文件)。
