Xuan Gong commented on YARN-1734:
---------------------------------
After YARN-16666 is checked in, we do have InputStream object returned from
ConfigurationProvider, so let us keep it.
The new patch includes changes in AdminService. I create a set which includes
function name, parameter type and parameter object for all refresh*s. And will
manually call them after transitionToActive. In that case, the active RM can
get the updated configuration.
A test case is also included.
> RM should get the updated Configurations when it transits from Standby to
> Active
