[jira] [Created] (YARN-2001) Persist NMs info for RM restart

Jian He created YARN-2001:
-----------------------------

             Summary: Persist NMs info for RM restart
                 Key: YARN-2001
                 URL: https://issues.apache.org/jira/browse/YARN-2001
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Jian He
            Assignee: Jian He


RM should not accept allocate requests from AMs until all the NMs have registered with RM. For that, RM needs to remember the previous NMs and wait for all the NMs to register.
This is also useful for remembering decommissioned nodes across restarts.
