For NMs talking with RM, you need to restart the NMs to take the configs into effect.
For the client talking with RM, you don't need to restart the RM.

my client aware about the fact the resource manager is down but I could not figure out. The
reason is that the call :  yarnClient.createApplication(); never return when the resource
manager is down. However it just stay in a loops and sleep after 10 iteration and continue
the same loops. Below you can find the logs. Any idea how to leave this loop ? is there any
parameter that control the number of seconds before giving up.
