我已經創建了4個節點的HDinsight集羣。當我發出命令「紗節點-list」,它表明:運行容器的天青數量是多少?
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
後,我提交蜂房的工作,它計算映射器(例如:900)和減速器(例如:100)。那麼如果我檢查節點詳細信息,它會顯示所有節點中值爲8的正在運行的容器。如果我提交簡單的作業,容器將值2或1隨機分配給任何工作節點。
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?
終於,找到了解決辦法。正在運行的容器的數量顯示節點大小的磁盤值。例如,如果我們選擇具有3個工作節點的D4 V2大小,則運行的容器數值將爲48.計算是(工作節點的否)*(D4 V2磁盤大小,即16)。 –
