[jira] [Updated] (YARN-1593) support out-of-proc AuxiliaryServices
[ https://issues.apache.org/jira/browse/YARN-1593?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Varun Vasudev updated YARN-1593: Attachment: SystemContainersandSystemServices.pdf Uploaded a document with our initial thoughts. This is not a comprehensive design document because we're interested in what folks in the community think about some of these issues. Once we have some feedback, we can do a second revision which can be closer to a design document. [~haibochen], [~kasha], [~asuresh], [~chris.douglas], [~jlowe] - we'd really appreciate your thoughts.
