Daniel Templeton commented on YARN-8480: ---------------------------------------- I read through both node attributes and rich placement constraints. Correct me if I'm wrong, but it looks to me like node attributes rely on the PCM from rich placement constraints for scheduling. It also looks to me like the PCM is an out-of-band scheduling process that skips the usual scheduling process. The amount of code that changed in YARN-7670 to support rich placement constraints in capacity scheduler was smallish, but the impact is fairly large. Yes, the patch for this JIRA does touch a lot of common files, but the changes are minor and non-invasive and will come with careful testing for performance impact. The patch already includes a huge amount of new unit tests (on top of what was added with resource types already) to make sure nothing is impacted as a result of this minor extension. > Add boolean option for resources > -------------------------------- > > Key: YARN-8480 > URL: https://issues.apache.org/jira/browse/YARN-8480 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Daniel Templeton > Assignee: Szilard Nemeth > Priority: Major > Attachments: YARN-8480.001.patch, YARN-8480.002.patch > > > Make it possible to define a resource with a boolean value. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
