--------------------------------------
Summary: NM restarts could lead to app failures
Key: YARN-3811
URL: https://issues.apache.org/jira/browse/YARN-3811
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.7.0
Reporter: Karthik Kambatla
Assignee: Karthik Kambatla
Priority: Critical
Consider the following scenario:
1. RM assigns a container on node N to an app A.
2. Node N is restarted
3. A tries to launch container on node N.
3 could lead to an NMNotYetReadyException depending on whether NM N has
registered with the RM. In MR, this is considered a task attempt failure. A few
of these could lead to a task/job failure.
