[jira] [Updated] (YARN-3842) NM restarts could lead to app failures
[ https://issues.apache.org/jira/browse/YARN-3842?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Kanter updated YARN-3842:
--------------------------------
Attachment: YARN-3842.001.patch
That makes sense. The patch is also a lot simpler; it just adds a retry policy for {{NMNotYetReadyException}}, and a test.

> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.7.0
> Reporter: Karthik Kambatla

> 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.
