Hudson commented on MAPREDUCE-5497:
-----------------------------------
SUCCESS: Integrated in Hadoop-Yarn-trunk #329 (See
[https://builds.apache.org/job/Hadoop-Yarn-trunk/329/])
MAPREDUCE-5497. Changed MRAppMaster to sleep only after doing everything else
but just before ClientService to avoid race conditions during RM restart.

> Since the '5s sleep' is for the purpose to let clients know the final states,
> put it after other services are stopped and only before stopping
> ClientService is enough. This can reduce some race conditions like
> MAPREDUCE-5471
