> Currently, we are sharing {{ReplayListenerBus}} for replaying the event logs of various apps.
> https://github.com/apache/spark/blob/v1.4.0/core/src/main/scala/org/apache/spark/deploy/history/FsHistoryProvider.scala#L226
> While replaying the event log for a particular app, we add an {{ApplicationEventListener}} to the bus.
> https://github.com/apache/spark/blob/v1.4.0/core/src/main/scala/org/apache/spark/deploy/history/FsHistoryProvider.scala#L391
> But we never remove it.
> This results in one {{ReplayListenerBus}} being associated with multiple {{ApplicationEventListener}}:

> We should either remove the listener from the bus or create a new bus for each app.
