Subject [jira] [Updated] (YARN-5292) NM Container lifecycle and state transitions to support for PAUSED container state.
Date Tue, 06 Dec 2016 15:39:59 GMT

     [ https://issues.apache.org/jira/browse/YARN-5292?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arun Suresh updated YARN-5292:
------------------------------
    Description: This JIRA addresses the NM Container and state machine and lifecycle changes
needed  to support pausing.  (was: YARN-2877 introduced OPPORTUNISTIC containers, and YARN-5216
proposes to add capability to customize how OPPORTUNISTIC containers get preempted.

In this JIRA we propose introducing a PAUSED container state.
When a running container gets preempted, it enters the PAUSED state, where it remains until
resources get freed up on the node then the preempted container can resume to the running
state.
 
One scenario where this capability is useful is work preservation. How preemption is done,
and whether the container supports it, is implementation specific.

For instance, if the container is a virtual machine, then preempt would pause the VM and resume
would restore it back to the running state.
If the container doesn't support preemption, then preempt would default to killing the container.

 )
