我有一个3节点设置运行Marathon，mesos-master，mesos-slave和Zookeeper并启用了HA配置，然后使用mesos-execute测试了一个简单的hello app的部署，并且它按预期工作。
现在一切都很好，所以我连接到Marathon并部署一个简单的应用程序来测试马拉松:( echo“hello”＆gt;＆gt;＆tmp / output.txt）但应用程序被吸入“等待”状态。< / p>
阻止Marathon使用mesos资源进行部署可能会出现什么问题？

应用程序永远处于“等待”状态 这意味着Marathon不会从Mesos接收“资源优惠”，允许它启动此应用程序的任务。最简单的失败是集群中没有足够的可用资源，或者其他框架都没有所有这些资源。您可以在Mesos UI中查看可用资源。请注意，必须在单个主机上提供所需的资源（例如CPU，内存，磁盘）。
如果您没有自己找到解决方案并且您创建了GitHub问题，请将Mesos / state端点的输出附加到错误报告中，以便我们可以检查可用的群集资源。
在您的情况下，应用程序角色要求和代理角色存在问题。您可以从UnfulfilledRole推断出它。
Marathon 1.4引入了有关卡住部署的信息。您可以查询/v2/queue并获取有关拒绝优惠的统计信息。
