我对NiFi和Ignite还是陌生的。我正在尝试使用PutIgniteCache处理器将FlowFiles流化为Ignite。但是，我收到错误java.lang.ExceptionInInitializerError。我具有PutIgniteCache的默认配置，并将Filename用作Ignite Cache条目标识符。
老实说，我缺少NiFi或Ignite的一些简单配置，以前有人遇到过此错误吗？
编辑：以下是我的NiFi的bootstrap.conf文件，其中添加了参数（17-23），以使Ignite在Java 9上运行。

答案 0 :(得分：0)
您似乎正在运行某些非常旧的Apache Ignite版本，该版本肯定无法在Java 9下运行。您应该升级到最新的Apache Ignite 2.7（并保留Java 9的那些选项）。
答案 1 :(得分：0)
目前无事可做... NiFi的ignite dependency是不支持Java 9的旧版本。您可以尝试自己用新版本重新编译它，或降级Java版本，与此同时，{ {3}}关于这个问题。
