(1)当Driver中的CoarseGrainedSchedulerBackend给CoarseGrainedExecutorBackend发送LaunchTask之后,CoarseGrainedExecutorBackend收到LaunchTask消息后,首先会反序列化TaskDescription。(2)Executor会通过launchTask执行Task,在launchTask方法中调用
I consistently see "Launch" errors due the system "seeing" an instance of the job already running. a. I logged on with the Service ID, and via the Task Mgr. I saw the .EXE come into view and disappeared after 2 minutes. This is the expected results. ...

Setting // this code during onCreate(Bundle savedInstanceState) or onResume() will keep the // activity hidden during this time, to avoid flickering. // This can only be done when a result is requested because // that guarantees we will get information back when the // activity is ...

Since tasks on generic worker are not guaranteed to be running in a container, a powershell instance is started on the task user's account. A user can then docker exec into the a running container, if there is one. Since: generic-worker v83.6.0 liveLog:boolean Enable [livelog](https:/...
that task is the only task running on the container instance. In this example, the container can use the full 1,024 CPU unit share at any given time. However, assume then that you launched another copy of the same task on that container instance. Each task is guaranteed a minimum of 51...
launchTask首先实例化TaskRunner,因为其继承自Runnable,所以在线程池threadPool中建立线程时,会在该独立运行的线程中自动执行run() def launchTask(context: ExecutorBackend, taskId: Long, serializedTask: ByteBuffer) { val tr=newTaskRunner(context, taskId, serializedTask) ...
