[jira] [Created] (YARN-141) NodeManager shuts down if it can't find the ResourceManager

             Summary: NodeManager shuts down if it can't find the ResourceManager
                 Key: YARN-141
                 URL: https://issues.apache.org/jira/browse/YARN-141
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Ahmed Radwan
            Assignee: Ahmed Radwan


When starting yarn services, and if the NodeManager is started but the ResourceManager is not. The NodeManager tries 10 times (the default setting), and then shuts down.

I understand that this default setting can be changed and possibly wait for a longer period, but I think it is better to keep the NodeManager trying without shutting down. This can accomodate cases where the ResourceManager is late to start for any problems and it will preserve the same behavior to what the DataNode does when it cannot find the NameNode at startup as it keeps trying without shutting down.
