Key: YARN-355
URL: https://issues.apache.org/jira/browse/YARN-355
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.0.0-alpha, 3.0.0, 0.23.6
Reporter: Daryn Sharp
Assignee: Daryn Sharp
Priority: Blocker
The RM performs a loopback connection to itself to renew its own tokens. If
app submissions consume all RPC handlers for {{ClientRMProtocol}}, then app
submissions block because it cannot loopback to itself to do the renewal.
