Problem Description

As it shows above, param 'maxRunningJob' use param 'wds.linkis.rm.instance' as the default value. If there are n entrance nodes， the total running task num will be n * param 'wds.linkis.rm.instance'。 Entrance服务中maxRunningJob参数默认值取wds.linkis.rm.instance。在集群有n个entrance实例时，总的任务运行数为n * wds.linkis.rm.instance 。

solutions

1, get the value of wds.linkis.rm.instance defined m, num of all entrance nodes in the cluster defined as n , the value of param 'maxRunningJob' is m / n defined as t 2, define the minimum running job param 'wds.linkis.entrance.runningjob.min' with default value 5. 3, the group set the minimum value between t and the value of 'wds.linkis.entrance.runningjob.min' . 1，用户配置wds.linkis.rm.instance 定义为m，集群所有entrance 数量定义为n，则初始最大运行任务数为m/n ，定义为t 2，定义entrance最小运行任务数 wds.linkis.entrance.runningjob.min = 5 3，用户队列group设置t和wds.linkis.entrance.runningjob.min中的最大值，作为最大运行数
