我正在研究以下内容的苍鹭教程：https://apache.github.io/incubator-heron/docs/getting-started/'
在遇到此错误之前我走得很远：
$: 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
我很新的苍鹭。知道是什么原因造成的吗？
答案 0 :(得分：0)
这不是真正的答案。评论太久了，所以我必须创建一个答案。...
到目前为止，很难说出这个问题，这是带有几乎最新代码fyi的预期输出。
