Jackie-Jiang opened a new pull request #3475: Enhance controller periodic task and scheduler
URL: https://github.com/apache/incubator-pinot/pull/3475
 
 
   For ControllerPeriodicTask:
   1. Random pick an initial delay of range 2-5 mins so each task does not start at the same time
   2. Make leadership information private to the class
   For PeriodicTaskScheduler:
   1. Filter out tasks with non-positive interval, so we can easily disable any task by setting the interval to an non-positive value
   2. Set the size of thread pool to be the same as number of tasks
   3. Reduce the run-time of PeriodicTaskSchedulerTest
