--------------------------------
Summary: Fair Scheduler chokes on unhealthy node reconnect
Key: YARN-1265
URL: https://issues.apache.org/jira/browse/YARN-1265
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager, scheduler
Affects Versions: 2.1.1-beta
Reporter: Sandy Ryza
Assignee: Sandy Ryza
Only nodes in the RUNNING state are tracked by schedulers. When a node
reconnects, RMNodeImpl.ReconnectNodeTransition tries to remove it, even if it's
in the RUNNING state. The FairScheduler doesn't guard against this.
I think the best way to fix this is to check to see whether a node is RUNNING
before telling the scheduler to remove it.
