[jira] [Commented] (YARN-8007) Support specifying placement
constraint for task containers in SLS
[ https://issues.apache.org/jira/browse/YARN-8007?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16389181#comment-16389181 ]
Jiandan Yang commented on YARN-8007:
-------------------------------------
Because currently MR specify placement constraints in the form of data locality, there is no need to specify placement constraint in MR job. I plan to implement specifying placement constraints in *stream type* app in SLS introduced by YARN-7732.
