Jun Gong updated YARN-3998: --------------------------- Attachment: YARN-3998.05.patch Attach a new patch to fix checkstyle errors. Test case errors are not related. > Add retry-times to let NM re-launch container when it fails to run > ------------------------------------------------------------------ > > Key: YARN-3998 > URL: https://issues.apache.org/jira/browse/YARN-3998 > Project: Hadoop YARN > Issue Type: New Feature > Reporter: Jun Gong > Assignee: Jun Gong > Attachments: YARN-3998.01.patch, YARN-3998.02.patch, > YARN-3998.03.patch, YARN-3998.04.patch, YARN-3998.05.patch > > > I'd like to add a field(retry-times) in ContainerLaunchContext. When AM > launches containers, it could specify the value. Then NM will re-launch the > container 'retry-times' times when it fails to run(e.g.exit code is not 0). > It will save a lot of time. It avoids container localization. RM does not > need to re-schedule the container. And local files in container's working > directory will be left for re-use.(If container have downloaded some big > files, it does not need to re-download them when running again.) > We find it is useful in systems like Storm. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
