    Description

      Since YARN-4234, we involve TimelineClient start and stop that would create different TimelineWriter according to the configuration. serviceStart() will create a TimelineWriter instance every time which will spawn several timer threads afterwards. If one TimelineClient get call start() multiple times for some reason (application bug or intentionally in some cases), the spawned timer threads will get leak.
