Wangda Tan commented on YARN-3971:
----------------------------------
Thanks [~bibinchundatt]/[~Naganarasimha] looking at this issue.
I think we need to fix AbstractService.state transition, only return started
after serviceStart() returns.
Do you know why we need to change service state to started before invoke
serviceStart()? It doesn't make sense to me actually...
+ [~vinodkv], who made this change in YARN-530.
