Subject [jira] [Updated] (YARN-1337) Recover containers upon nodemanager restart
Date Mon, 12 May 2014 15:17:15 GMT

     [ https://issues.apache.org/jira/browse/YARN-1337?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jason Lowe updated YARN-1337:
-----------------------------

    Description: To support work-preserving NM restart we need to recover the state of the
containers when the nodemanager went down.  This includes informing the RM of containers that
have exited in the interim and a strategy for dealing with the exit codes from those containers
along with how to reacquire the active containers and determine their exit codes when they
terminate.  The state of finished containers also needs to be recovered.  (was: To support
work-preserving NM restart we need to recover the state of the containers that were active
when the nodemanager went down.  This includes informing the RM of containers that have exited
in the interim and a strategy for dealing with the exit codes from those containers along
with how to reacquire the active containers and determine their exit codes when they terminate.)
        Summary: Recover containers upon nodemanager restart  (was: Recover active container
state upon nodemanager restart)

Updating headline and description to note that this task also includes recovering the state
of finished containers as well.
