我正在学习在这里找到的苍鹭教程：https://apache.github.io/incubator-heron/docs/getting-started/'
在遇到此错误之前，我没有走多远：
$: heron activate local WindowedWordCountTopology
[2019-02-01 15:55:11 +0000] [INFO]: Using cluster definition in /home/<my-user>/.heron/conf/local
[2019-02-01 15:55:11 +0000] [ERROR]: Failed to get scheduler location from state manager
[2019-02-01 15:55:11 +0000] [ERROR]: Failed to activate topology: WindowedWordCountTopology
我对苍鹭很陌生。知道是什么原因造成的吗？
这不是一个真正的答案。评论太长了，所以我必须创建一个答案......
到目前为止很难说出问题，这是几乎最新的代码仅供参考的预期输出。
