[GitHub] [shardingsphere-elasticjob] Wjcccccccccc commented on issue #1995: Job doesn't execute after scheduling

Wjcccccccccc commented on issue #1995:
URL: https://github.com/apache/shardingsphere-elasticjob/issues/1995#issuecomment-943112212


   **Additional infomation:**
   I start two kinds of jobs A and B **in the meantime.**
   A is scheduled  every 5 second with cron `*/5 * * * * ?`
   B is scheduled to shutdown A after 5 minutes with a specified time point by cron `00 05 12 12 12 ?`, OneOffJobBootstrap is not suitable here because it needs to trigger by an Event, so I have to use ScheduleJobBootstrap with a specified time point.
   
   now I have a pressure test to start A and B 100 times. sometimes the A and B aren't scheduled, so I find the log
   ```
   Elastic job: ignored exception for: KeeperErrorCode = NoNode for /jato-web_test/pk_end_2487/sharding/0/instance
   ```
   
   I guess it is the slowness of Elasticjob's sharding that impact the job, so the job can't get the instance to execute when the time point is coming.
