Steve Loughran updated YARN-530:
--------------------------------
Attachment: YARN-117-019.patch
# make sure addService, removeService and service iteration are all thread safe
-eliminates risk of concurrency problems if the service list is changed during
init/start/stop of children. As these methods are protected, a subclass would
have to do this in another thread -or make the methods public
# composite service policy is switched to stop all services that are STARTED or
INITED
> Define Service model strictly, implement AbstractService for robust
> subclassing, migrate yarn-common services
> -------------------------------------------------------------------------------------------------------------
