Robert Kanter reassigned YARN-3811: ----------------------------------- Assignee: Robert Kanter (was: Karthik Kambatla) [~kasha] said I can take this over. > 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: Robert Kanter > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
