Quartz Scheduler: Trigger some jobs on every cluster node and some only once per cluster

阅读更多关于 Quartz Scheduler: Trigger some jobs on every cluster node and some only once per cluster

问题 I am using Quartz Scheduler as a Spring bean in a clustered environment. I have some jobs annotated with @NotConcurrent and they are running once per cluster (i.e. only in one node, only in one thread). Now I need to run one job on every node of the cluster. I removed the @NotConcurrent annotation, but it only run on every thread on one machine. It does not get fired on other nodes. What should I annotate the job with? Example: Job1 NotConcurrent annotated is scheduled at midnight => It fires

Get an instance of the scheduler that is being run on a Windows service

阅读更多关于 Get an instance of the scheduler that is being run on a Windows service

Let us say I have prepared my Quartz.NET as a Windows service and it is currently being run (with an ADOJobStore running on Sqlite ). I need to take control of this service on my Windows application so I can stop it, start it, add and remove jobs from it, etc. How can I get an instance of this scheduler? Sorry if it sounds like a simple question for you, but the documentation on Quartz.NET seems nowhere near enough. There are only a few people who know about it and they already have their lives to live. Update: quartz.config file of my service # You can configure your scheduler in either

Need job scheduler in asp.net

阅读更多关于 Need job scheduler in asp.net

问题 We have a website where we need a scheduler to receive notifications (e-mail) on specific time. eg. a person setting reminder at 5 PM to attend the meeting at 4:45 PM, will receive email at 4:45 PM about same. As this site is hosted on shared server, we don't have any control over the server to run any SQL Job or scheduler application. Is there anything in asp.net which can help in this scenario? 回答1: How about this: Simulate a Windows Service using ASP.NET to run scheduled jobs. At one point

Triggering spark jobs with REST

阅读更多关于 Triggering spark jobs with REST

I have been of late trying out apache spark . My question is more specific to trigger spark jobs. Here I had posted question on understanding spark jobs. After getting dirty on jobs I moved on to my requirement. I have a REST end point where I expose API to trigger Jobs, I have used Spring4.0 for Rest Implementation. Now going ahead I thought of implementing Jobs as Service in Spring where I would submit Job programmatically, meaning when the endpoint is triggered, with given parameters I would trigger the job. I have now few design options. Similar to the below written job, I need to maintain

How jobs are assigned to executors in Spark Streaming?

阅读更多关于 How jobs are assigned to executors in Spark Streaming?

Let's say I've got 2 or more executors in a Spark Streaming application. I've set the batch time of 10 seconds, so a job is started every 10 seconds reading input from my HDFS. If the every job lasts for more than 10 seconds, the new job that is started is assigned to a free executor right? Even if the previous one didn't finish? I know it seems like a obvious answer but I haven't found anything about job scheduling in the website or on the paper related to Spark Streaming. If you know some links where all of those things are explained, I would really appreciate to see them. Thank you.

Part of my question, how I can set up a job with less then 15 minutes interval in "Nougat", was answerd by "blizzard" in his answer here: Job Scheduler not running on Android N He explained the problem and suggested to use the following workaround: JobInfo jobInfo; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { jobInfo = new JobInfo.Builder(JOB_ID, serviceName) .setMinimumLatency(REFRESH_INTERVAL) .setExtras(bundle).build(); } else { jobInfo = new JobInfo.Builder(JOB_ID, serviceName) .setPeriodic(REFRESH_INTERVAL) .setExtras(bundle).build(); } However, using the suggested
