Subject Re: what happens to a client attempting to get a new app when the resource manager is already down
Date Sun, 02 Feb 2014 16:06:23 GMT
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.
