Subject [jira] [Commented] (YARN-6619) AMRMClient Changes to use the PlacementConstraint and SchcedulingRequest objects
Date Wed, 17 Jan 2018 01:21:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16328105#comment-16328105
] 

Wangda Tan commented on YARN-6619:
----------------------------------

[~kkaranasos] , is this supported? 
{quote}bq.  This way we can reserve the {{addPlacementConstraint}} API for cases that
a client wants to update the constraints.
{quote}
IIUC, the only way to update PlacementConstraint, as well as pending ResourceSizing, is to
send a new SchedulingRequest correct? If there's no separate updatePlacementConstraint API,
I suggest to remove addPlacementConstraint from AMRMClient as of now and add it back when
needed.
