我已经创建了4个节点的HDinsight集群。当我发出命令“纱节点-list”,它表明:运行容器的天青数量是多少?
Node-Id Node-State Node-Http-Address Number-of-Running-Containers
10.x.x.x:xxxxx RUNNING 10.x.x.x:xxxxx 0
10.x.x.x:xxxxx RUNNING 10.x.x.x:xxxxx 0
10.x.x.x:xxxxx RUNNING 10.x.x.x:xxxxx 0
10.x.x.x:xxxxx RUNNING 10.x.x.x:xxxxx 0
后,我提交蜂房的工作,它计算映射器(例如:900)和减速器(例如:100)。那么如果我检查节点详细信息,它会显示所有节点中值为8的正在运行的容器。如果我提交简单的作业,容器将值2或1随机分配给任何工作节点。
1. we know that, the mapper/reducer job are assigned to worker nodes. here, is it 4 worker nodes are processing the work or containers are processing?
2. basically, what is number of containers.
3. how the value of running containers assigned/changed?
终于,找到了解决办法。正在运行的容器的数量显示节点大小的磁盘值。例如,如果我们选择具有3个工作节点的D4 V2大小,则运行的容器数值将为48.计算是(工作节点的否)*(D4 V2磁盘大小,即16)。 –
