[jira] [Updated] (YARN-2037) Add restart support for Unmanaged AMs

     [ https://issues.apache.org/jira/browse/YARN-2037?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Botong Huang updated YARN-2037:
-------------------------------
    Attachment: YARN-2037.v1.patch

v1 patch uploaded. For work preserving UAM restart (one with flag  {{KeepContainersAcrossApplicationAttempts}} in {{ApplicationSubmissionContext}} set), we are not increasing the attempt id. Instead, RM directly allows the {{registerApplicationMaster}} call and returns the list of running containers of this UAM attempt back.
