Apache Nifi：PutHDFS 处理器问题 - PutHDFS 无法写入 HDFS java.lang.NoClassDefFoundError：org/apache/hadoop/conf/Configurable

问题描述 投票：0回答：1

我正在使用 Apache NIFI 

1.28
版本，我正在尝试创建一个简约的数据流，在其中生成数据并希望在“HDP（Hortonworks 数据平台）2.5.0”中摄取
HDFS
，我得到了以下错误，

下面是

puthdfs
处理器配置

puthdfs processor

下面是处理器组的整个数据流以及错误：

Complete Dataflow plus error

我还添加了一个简约的 

core-site.xml
配置，我从 
HDP 2.5
导入并放置在 
/conf
目录中，并在 puthdfs 
hdfs-site.xml
中与 
processor
一起配置其路径。

我通过在 Windows 11 计算机上从技术堆栈从 

HDP2.5
切换到独立的 hadoop 安装来解决所有这些问题。由于 
HDP2.5
没有更多可用支持，这就是为什么在复制时无法解析

的内部 ip。以下
hdfs-site.xml
和
core-site.xml
我已包含在apache nifi安装目录中，即
