Robert Parker updated YARN-819: ------------------------------- Attachment: YARN-819-2.patch > ResourceManager and NodeManager should check for a minimum allowed version > -------------------------------------------------------------------------- > > Key: YARN-819 > URL: https://issues.apache.org/jira/browse/YARN-819 > Project: Hadoop YARN > Issue Type: Sub-task > Components: nodemanager, resourcemanager > Affects Versions: 2.0.4-alpha > Reporter: Robert Parker > Assignee: Robert Parker > Attachments: YARN-819-1.patch, YARN-819-2.patch > > > Our use case is during upgrade on a large cluster several NodeManagers may > not restart with the new version. Once the RM comes back up the NodeManager > will re-register without issue to the RM. > The NM should report the version the RM. The RM should have a configuration > to disallow the check (default), equal to the RM (to prevent config change > for each release), equal to or greater than RM (to allow NM upgrades), and > finally an explicit version or version range. > The RM should also have an configuration on how to treat the mismatch: > REJECT, or REBOOT the NM. -- This message is automatically generated by JIRA.
