Subject [jira] [Updated] (YARN-3842) NM restarts could lead to app failures
Date Mon, 22 Jun 2015 21:07:03 GMT

]

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.

> 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.
