Mesos DCOS不安装Kafka

Question

我正试图在Mesos上安装Kafka。安装似乎已经成功。

vagrant@DevNode:/dcos$ dcos package install kafka 
This will install Apache Kafka DCOS Service. 
Continue installing? [yes/no] yes 
Installing Marathon app for package [kafka] version [0.9.4.0] 
Installing CLI subcommand for package [kafka] version [0.9.4.0] 
New command available: dcos kafka 
The Apache Kafka DCOS Service is installed: 
    docs - https://github.com/mesos/kafka 
    issues - https://github.com/mesos/kafka/issues 

vagrant@DevNode:/dcos$ dcos package list 
NAME VERSION APP  COMMAND DESCRIPTION 
kafka 0.9.4.0 /kafka kafka Apache Kafka running on top of Apache Mesos 

但是kafka任务未启动。

vagrant@DevNode:/dcos$ dcos kafka 
Error: Kafka is not running 
vagrant@DevNode:/dcos$ 

Marathon UI说服务是waiting。看起来它不接受分配给它的资源。更多日志here。

不知道为什么马拉松不喜欢这样的报价。我确信有足够的资源。

Answer 1

马拉松正在等待有足够资源的报价给卡夫卡调度员。它拒绝的报价似乎没有任何cpu或内存。您看到的具有足够资源的优惠已经为角色“slave_public”静态保留。

卡夫卡调度程序将与角色*一起运行。您的群集在默认角色*中缺乏足够的资源。这是与私人奴隶相关的角色。

您应该查看mesos/state并查看具有“*”角色的可用资源。
