jobs

问题 I used to launch my Hadoop job with the following long start = new Date().getTime(); boolean status = job.waitForCompletion(true); long end = new Date().getTime(); This way I could measure the time taken by the job once it ends directly in my code. Now I have to use the JobControl in order to express dependencies between my jobs: JobControl jobControl = new JobControl("MyJob"); jobControl.addJob(job1); jobControl.addJob(job2); job3.addDependingJob(job2); jobControl.addJob(job3); jobControl

问题 I have been working with Powershell for a time now, it is not the ideal programming environment, but got stuck with my program. My program is an GUI with a marquee progressbar and a search job. What my program does: After you run the script with Powershell it will restart Powershell in STA mode if the mode is MTA. After that it will ask for a folder location. After you entered the folder location it will start the search job and will search the location for files. Every file will be stored

问题 I am using WorkManager to schedule some tasks but the problem is that work manager is executing those tasks { doWork() } more than once in a single call. I am using: 'android.arch.work:work-runtime:1.0.0-alpha08' I have tried using -alpha07,06,05,04. But I have same issue. Sometimes it even executes 5-6 times at once Here is the code: public class MyWorker extends Worker { @NonNull @Override public Result doWork() { Log.i("CountWorker","0"); sendNotification("Notice", "A notice was sent");

问题 How to execute a SQL Server Job on AppHarbor database? 回答1: I got the answer to my earlier posted query. SQL server jobs are executed on AppHarbor as Background worker. The process is simple. 1. Create a windows job (any project that outputs an exe). 2. Integrate job with Quartz for scheduling 3. Upload to AppHarbor. 4. If you're already using a web or background worker, you may need to get extra subscription for a background worker. The background worker automatically picks up the exe and

问题 I would like to launch a non-blocking UI from a parent Powershell script and receive UI messages like button clicks from the child job. I have this kind of messaging working using WinForms, but I prefer to use ShowUI because of how much less code it takes to create a basic UI. Unfortunately, though, I haven't found a way to send messages back to the parent job using ShowUI. [Works] Forwarding Events When Using Start-Job Using Start-Job, forwarding events from a child to a parent job is rather

问题 I got a JobExecutionListener as follows: public class JobListener implements JobExecutionListener { @Override public void beforeJob(final JobExecution jobExecution) { // do some work with the jobExecution } @Override public void afterJob(final JobExecution jobExecution) { // do some work with the jobExecution } } I want to write a test for my JobListener and i am wondering myself if i need to mock the JobExecution. Do you think that will be ok, or is there another nice solution to this? 回答1:

问题 I have a grails application in which the user uploads a document and my application does various things with the uploaded file. Some of these tasks take a long time so the user has to wait to see the next page. I want to change this behavior such that the user uploads the file and then immediately sees the next page. In the background the uploaded file will be queued. Later I want to pick-up files from the queue and process them in the order they were received. What are some options available

问题 I am implementing quartz.net scheduler to my project, and have some questions about the workings of this library: What happens if one job raises an exception without a catch block (unhandled exception)? Would this cause the process to terminate and AppDomain Unloading? Would other jobs suffer? Does Quartz.net lib try to restart jobs that raised unhandled exceptions? Or should I implement it manually in my project? Thanks. 回答1: From what I can determine being a user of Quartz.net myself. If

问题 I have a small cluster with nodes A, B, C and D. Each node has 80GB RAM and 32 CPUs. I am using Slurm 17.11.7. I performed the following benchmark tests: If I run a particular Java command directly on terminal on node A, I get an result in 2minutes. If I run the same command with an "single" array job (#SBATCH --array=1-1), I get an result again in 2minutes. If I ran the same command with same parameters with an array job on slurm only on node A, I get the output in 8mininutes, that is, it is

问题 I have a procedure which is being called at server side and I need to make it asynchronous. So I have created another proc in which I'll create Oracle'Job and this will call that proc in its job_action. Proc is: PROCEDURE upload_csv_file_data(a_what_to_do IN VARCHAR2, a_logon_user IN VARCHAR2, a_csv_data IN CLOB) IS v_job_action VARCHAR2(32676); /*v_log_error VARCHAR2(32676);*/ v_job_name VARCHAR2(100); BEGIN v_job_action := 'process_csv_file_data(''' || a_what_to_do || ''',''' || a_logon
