Daniel Templeton commented on YARN-10854: ----------------------------------------- In principle the change looks fine to me. I'd like the docs in the XML file to be a bit more explicit about what this property does. If you know about the behavior of the include and exclude lists, the explanation is just barely enough to know what the flag does. It would be better to be more verbose, provide some context, make it easier to understand without reading source code. > Support marking inactive node as untracked without configured include path > -------------------------------------------------------------------------- > > Key: YARN-10854 > URL: https://issues.apache.org/jira/browse/YARN-10854 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Reporter: Tao Yang > Assignee: Tao Yang > Priority: Major > Attachments: YARN-10854.001.patch > > > Currently inactive nodes which have been decommissioned/shutdown/lost for a > while(specified expiration time defined via > {{yarn.resourcemanager.node-removal-untracked.timeout-ms}}, 60 seconds by > default) and not exist in both include and exclude files can be marked as > untracked nodes and can be removed from RM state (YARN-4311). It's very > useful when auto-scaling is enabled in elastic cloud environment, which can > avoid unlimited increase of inactive nodes (mostly are decommissioned nodes). > But this only works when the include path is configured, mismatched for most > of our cloud environments without configured white list of nodes, which can > lead to easily control for the auto-scaling of nodes without further security > requirements. > So I propose to supportĀ marking inactive node as untracked without configured > include path, to be compatible with the former versions, we can add a switch > config for this. > Any thoughts/suggestions/feedbacks are welcome! -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
