Arun Suresh updated YARN-5972: ------------------------------ Assignee: Hitesh Sharma > Add Support for Pausing/Freezing of containers > ---------------------------------------------- > > Key: YARN-5972 > URL: https://issues.apache.org/jira/browse/YARN-5972 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Arun Suresh > Assignee: Hitesh Sharma > > 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. > Instead of preempting a running container, the container can be moved to a > PAUSED state, where it remains until resources get freed up on the node then > the preempted container can resume to the running state. > Note that process freezing this is already supported by 'cgroups freezer' > which is used internally by the docker pause functionality. Windows also has > OS level support of a similar nature. > 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 call would > pause the VM and resume would restore it back to the running state. > If the container executor / runtime doesn't support preemption, then preempt > would default to killing the container. > -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
