Subject [jira] [Commented] (YARN-7745) Allow DistributedShell to take a placement specification for containers it wants to launch
Date Thu, 18 Jan 2018 21:13:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16331230#comment-16331230

Wangda Tan commented on YARN-7745:
----------------------------------

Patch looks good, +1, will commit in a couple of hours in case anybody else has comments.

It looks this patch doesn't have any test, [~asuresh] could you file a follow-up patch to
add e2e tests for placement constraints.

> This is add a '-placement_spec' option to the distributed shell client. Where the user
can specify a string-ified specification for how it wants containers to be placed.
> For eg:
> {noformat}
> $ yarn org.apache.hadoop.yarn.applications.distributedshell.Client –jar \
> $YARN_DS/hadoop-yarn-applications-distributedshell-$YARN_VERSION.jar \
>  -shell_command sleep -shell_args 10 -placement_spec <placementspecification>
> {noformat}
