apache-nifi - NiFi : Failed to connect node to cluster because local flow is different than cluster flow

Question

重新启动服务器后，NiFi 无法启动。在服务器重新启动之前，我能够毫无问题地关闭/启动 NiFi。

我确保所有节点上的 3 个配置文件(flow.xml.gz、authorizations.xml 和 users.xml)都相同。

此外，通过删除 zookeeper 集群中 NiFi 的 znode，排除了任何 zookeeper 损坏问题。

我在 NiFi 1.9.1

任何帮助都受到高度赞赏。

这意味着authorizations.xml 或users.xml 中存在差异，很可能是authorizations.xml。我会尝试将这两个文件从其他节点之一复制到出现问题的节点，这将确保它们完全相同。
