我已经在几种不同的口味中看到了同样的问题。然而，发布的解决方案要么与我的问题无关，要么根本就没有解决方案。
Apache Nifi 1.5
Java JDK 9.0.4 - NiFi是否支持此版本？
JAVA_HOME=C:\Program Files\Java\jdk-9.0.4
我有一个想法，也许Apache NiFi不能与JDK 9.0.4版本一起工作但是我无法找到任何文档说明哪个版本的JDK Apache NiFi兼容，所以我的假设是它没有＆ ＃39; t。。
我在nifi-app.log和nifi-bootstrap.log文件中看到的警告和错误均与“权限”相关。另一个可能的原因（猜测）可能是由security properties文件中的nifi.properties引起的。我设置了nifi.sensitive.propr.key但是我看到了另一个我未设置的属性：nifi.sensitive.props.key.protected。
由于nifi-user.log文件中没有任何内容，我已将其放在两个日志文件的内容之下：

app.log: java.util.ServiceConfigurationError：org.apache.nifi.authorization.AccessPolicyProvider：org.apache.nifi.authorization.FileAccessPolicyProvider无法获取公共no-arg构造函数bootstrap log:应更改权限，以便只有所有者才能读取此文件
