5.How will the Fair Scheduler handle these two jobs?
You have a cluster running with the fair Scheduler enabled. There are currently no jobs running on the cluster, and you submit a job A, so that only job A is running on the cluster. A while later, you submit Job B. Now Job A and Job B are running on the cluster at the same time. How will the FairScheduler handle these two jobs?A.When Job B gets submitted, it will get assigned tasks, while job A continues to run with fewer tasks.
B.When Job B gets submitted, Job A has to finish first, before job B can gets scheduled.C.When Job A gets submitted, it doesn’t consumes all the task slots.D.When Job A gets submitted, it consumes all the task slots.问题: 公平调度器对这两个jobs怎样处理？解析: AD 当只有一个job A在运行,这个job A会使用整个集群的 任务solts;当另外一个job B被提交,那么任务solts会被释放分配给新的job B,然而job A则会继续使用少些的任务solts,运行着。
