[jira] [Reopened] (YARN-1018) prereq check for AMRMClient.ContainerRequest relaxLocality flag wrong

["Steve Loughran (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-1018?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steve Loughran reopened YARN-1018:
----------------------------------


I'm re-opening this as it prevents containers without placement constraints being requested with the same priority as containers with restrictions. This check says "you can't flip the locality bit", while another check in the client says "you can't have different locality restrictions in the same priority"
