Steve Loughran commented on YARN-4527:
--------------------------------------
the yarn service state machine guarantees that serviceStart() will not be
called more than once
> Possible thread leak if TimelineClient.start() get called multiple times.

> 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.
