Weiwei Yang commented on YARN-7920: ----------------------------------- Hi [~leftnoteasy],[~kkaranasos] Sorry for the late response, I was on vacation. {quote}for the md.vm format, any advantages in this format {quote} this format of markdown file can help to substitute ${project.version} variable to the under-building version. I think we need to rename it back otherwise the doc will be looking like following {code} $ yarn org.apache.hadoop.yarn.applications.distributedshell.Client -jar share/hadoop/yarn/hadoop-yarn-applications-distributedshell-${project.version}.jar -shell_command sleep -shell_args 10 -placement_spec PlacementSpec {code} what do you think? > Simplify configuration for PlacementConstraints > ----------------------------------------------- > > Key: YARN-7920 > URL: https://issues.apache.org/jira/browse/YARN-7920 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Wangda Tan > Assignee: Wangda Tan > Priority: Blocker > Fix For: 3.1.0 > > Attachments: YARN-7920.001.patch, YARN-7920.002.patch, > YARN-7920.003.patch, YARN-7920.004.patch, YARN-7920.005.patch, > YARN-7920.006.patch > > > Currently it is very confusing to have the two configs in two different files > (yarn-site.xml and capacity-scheduler.xml). > > Maybe a better approach is: we can delete the scheduling-request.allowed in > CS, and update placement-constraints configs in yarn-site.xml a bit: > > - Remove placement-constraints.enabled, and add a new > placement-constraints.handler, by default is none, and other acceptable > values are a. external-processor (since algorithm is too generic to me), b. > scheduler. > - And add a new PlacementProcessor just to pass SchedulingRequest to > scheduler without any modifications. -- 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
