提交拓扑后命令状态停止"Creating job WordCountTopology"
The command status stop "Creating job WordCountTopology" after submit a Topology
我尝试使用 Apache Mesos、Apache Aurora、ZooKeeper 和 HDFS 构建 Heron 集群。但是，当我在完成后提交 WordCountTopology 时，命令输出如下： Stopping the "Creating job WordCountTopology".

非常感谢您的帮助。
这个问题是集群资源不足造成的。当Aurora Scheduler将实例调度到Heron集群中的worker节点时，如果某个worker节点没有足够的资源分配一个实例，就会导致该实例挂起，等待集群中资源充足的工作节点出现。
于是通过增加Heron集群中worker节点的RAM资源解决了这个问题。
