I take your point, I think virtual sleep task type will reduce back-end(like hadoop or spark and so on) system pressure. not use sleep some time in shell task, this sleep task will also start a real job, it's not good idea.
some other users also need this feature. so I think you can submit an issue about this feature, and leave a message "you are implementing it", then submit a PR when you implement it Best Regards --------------- DolphinScheduler(Incubator) PPMC Lidong Dai 代立冬 [email protected] --------------- boyi <[email protected]> 于2020年6月5日周五 下午3:39写道： > hi: > > > It's not necessary, it's just that our project has specific requirements > > > We use the worker node to run a virtual sleep task instead of using shell > -------------------------------------- > BoYi ZhangE-mail : [email protected] > On 06/5/2020 15:26，leon bao<[email protected]> wrote： > if need a sleep task without doing nothing, you can implement this > requirement by a shell ? > > wu shaoj <[email protected]> 于2020年6月4日周四 下午1:51写道： > > New task type just for sleeping is not recommended to add, which makes no > sense. > I thinks this is unreasonable .
