Subject Re: what happens to a client attempting to get a new app when the resource manager is already down
Date Mon, 03 Feb 2014 14:52:16 GMT
Thank you very much. 
One last question: Do you think those parameters setting require restarting the cluster?

Thanks

Hi 
All entities including NM and client etc. use the same RMProxy to talk with RM. The retry
behavior is controlled by the following two configs.
yarn.resourcemanager.connect.max-wait.ms controls Maximum time to wait to establish connection
to ResourceManager.

yarn.resourcemanager.connect.retry-interval.ms controls How often to try connecting to the
ResourceManager.

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.
