Apache的generated.java文件位置

Question

我正在犯以下错误：

ERROR CodeGenerator: failed to compile: org.codehaus.commons.compiler.CompileException: File 'generated.java', Line 739, Column 34: A method named "toString" is not declared in any enclosing class nor any supertype, nor through a static import
org.codehaus.commons.compiler.CompileException: File 'generated.java', Line 739, Column 34: A method named "toString" is not declared in any enclosing class nor any supertype, nor through a static import

在哪里可以找到这个'generated.java'文件？

我正在使用一个主节点和3个工作节点.

SPARK版本: 2.3.0

您可以通过调用以下方法将其转储到stdout：

dataset.queryExecution().debug().codegen();
