NiFiCoreException：无法启动流量控制器

当使用嵌入式Zookeeper 3.5.5在群集模式下启动Nifi 1.9.2时，出现此错误。

我使用Java 1.8.nifi成功地分别启动了三个zookeeper 3.5.5。

此错误使我花费了太多时间，但我无法拒绝它。 有人能帮我吗？ 提前THX。

答案 0 :(得分：1)

该错误来自于ZooKeeper客户端代码，该代码解析了zookeeper.properts中的“ server.XXX”条目，并尝试将条目“：”分开并获得索引0和索引1的部分，没有索引1，因此其获取数组索引超出范围。这基本上意味着您的一个服务器条目的格式不是host：port或host：port：port。

此外，如评论中所述，如果您设置nifi.state.management.embedded.zookeeper.start = true，则您不应该启动自己的ZooKeeper。您可以使用嵌入式或外部，但不能同时使用。
