我正在尝试设置drillv1.18运行。面临以下错误。
drill-override.conf指向运行在12181端口的zookeeper。在分布式模式下启动时，失败了，输出日志如下。 但在嵌入式模式下没有问题。看起来像是权限问题，但是zookeeper、drill、zookeeper data-dir都在同一个用户下运行。

1.17版本在分布式模式下启动没有问题。
问题出在zookeeper的版本上。也许您使用的是 3.4.X 版本，但当前版本的 Drill 需要 3.5.X。jars/ext/zookeeper-3.5.7.jar 和 jars/ext/zookeeper-jute-3.5.7.jar 与您的zookeeper版本相对应的罐子。
