Custom Object parameters within Jobs using Quartz-scheduler

依然范特西╮ 提交于 2019-12-04 20:17:39
I am testing out Quartz to schedule a job. However the job contains 3 non-serializable parameters. I have created a sample application below indicating how I am implementing the functionality. Does anyone know how I can use custom objects as parameters using Quartz? Below is the trigger which schedules the job, I have commented the area which is giving me issues. public class Trigger { public void run() throws Exception { SchedulerFactory sf = new StdSchedulerFactory(); Scheduler sched = sf.getScheduler(); Date startTime = DateBuilder.nextGivenSecondDate(null, 15); JobDetail job = newJob

Evaluate complex time patterns

拜拜、爱过 提交于 2019-12-04 05:26:42
问题 I would like to define and evaluate ocurrences of some very complex time patterns that cannot be handled by CRON expressions easily. Is there any library that help me to do that? For example: I would like it to occur every 25 seconds. I would like to occur only first and last day of month. But first day of month should gets me resolution of 5 minutes betwen 9:00AM and 11:00AM. The last day of month should evaluate to 5:00AM. I would like to create very complex time pattern that do something

Firebase jobdispatcher not triggering within specified window

I am implementing Firebase Jobdispatcher with trigger time specified between 10 to 20 seconds. This is my code to schedule a job: public static void scheduleCompatibleJob(Context context) { FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(context)); Job myJob = dispatcher.newJobBuilder() .setService(DataTrackerJobService.class) // the JobService that will be called .setTag("api_trigger") .setRecurring(true) .setLifetime(Lifetime.FOREVER) .setTrigger(Trigger.executionWindow(10, 20)) // 10 to 20 seconds .setReplaceCurrent(true) .setRetryStrategy(RetryStrategy

What is Spark Job ?

问题 I have already done with spark installation and executed few testcases setting master and worker nodes. That said, I have a very fat confusion of what exactly a job is meant in Spark context(not SparkContext). I have below questions How different is job from a Driver program. Application itself is a part of Driver program? Spark submit in a way is a job? I read the Spark documention but still this thing is not clear for me. Having said, my implementation is to write spark jobs

Adding dynamic cron jobs to GAE

问题 In GAE we can add cron job manually by editing the cron.xml file <?xml version="1.0" encoding="UTF-8"?> <cronentries> <cron> <url>/cron/addCount/1</url> <description>Add count + 1 every 1 minutes</description> <schedule>every 1 minutes</schedule> </cron> </cronentries> Is there any way that I can make a user interface and create/update/delete as many cron jobs on the fly.That means after I deploy to GAE , I should be able to update the cron.xml ? Or is there a work around so that I can create

Can Quartz Scheduler Run jobs serially?

痞子三分冷 提交于 2019-12-01 18:16:30
I'm looking into using Quartz Scheduler, and I was wondering if it was possible to schedule jobs not by time, but when another job finishes. So, when Job A is done, it starts Job B. When that's done, it starts Job C, etc. Job A -> Job B -> Job C -> Job A... continuously. Is this the right tool for the job? Or should I be looking into something else? Check out JobChainingJobListener , built-in to Quartz (bold mine): Keeps a collection of mappings of which Job to trigger after the completion of a given job. If this listener is notified of a job completing that has a mapping, then it will then
