---------------------------------
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.
