   > The reason has been found, Because ZooKeeper is unstable, it frequently disconnects.I am not aware of the specific implementation of Dolphinscheduler in this function.At this point, if ZooKeeper is unstable, you may have a bug where the same workflow node executes multiple times.I don't know what you think about that?Will you consider fixing the problem?
   > Thanks

   > 原因找到了，是因为zookeeper不稳定，存在断连的情况。但是我不是很清楚dolphinscheduler在这一块的具体实现。目前来看，如果zookeeper不稳定，有可能会出现同一个工作流节点执行多次的bug。不知道大家对这个问题怎么看？是否会考虑修复这个问题？
   > 谢谢。
