apache-nifi - MiNiFi-Tutorial 失败，工具包错误：Connection with id ... has invalid destination id
问题描述
我遵循了本教程：MiNiFi 入门
因此，input port在我的根进程组和 MiNiFi 进程组中有一个。,MiNiFi Process Group包含 a Tail File Processor, aRemote Process Group和它们之间的连接。
在MiNiFi Process Group我保存模板之后，我从模板列表下载它并运行命令：
minifi-toolkit-0.5.0\bin\config.bat transform minifi\MiNiFi2.xml minifi\minifi_config\config.yml
但它失败并说：
The JAVA_HOME environment variable is not defined correctly.
Instead the PATH will be used to find the java executable.
There are validation errors with the template, still outputting YAML but it will need to be edited.
Connection with id 10de7342-41ef-37a5-0000-000000000000 has invalid destination id 9b02eb45-3c2d-3fb4-91cf-880d5038c0cd
我重新创建了所有内容，但问题仍然存在。
这是我的模板：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<template encoding-version="1.3">

解决方案
编辑：
工具包中似乎存在一个错误（ @seb 报告的MINIFI-521），其中 targetId 在模板中用作输入端口 ID，但连接 ID 未正确映射。
以前的：
如果我没记错的话，工具包期望它处理的模板是完全独立的。
该模板正在引用来自根进程组的输入端口。
当仅导出和转换模板以与 MiNiFi 一起使用时，这将导致它丢失。
我建议将您的输入端口向下移动到您要为其创建模板的进程组中。
