[jira] [Updated] (YARN-5220) Scheduling of OPPORTUNISTIC containers
through YARN RM
[ https://issues.apache.org/jira/browse/YARN-5220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Konstantinos Karanasos updated YARN-5220:
-----------------------------------------
Description:
In YARN-2882, we introduced the notion of OPPORTUNISTIC containers, along with the existing GUARANTEED containers of YARN.
OPPORTUNISTIC containers are allowed to be queued at the NMs (YARN-2883), and are executed as long as there are available resources at the NM. Moreover, they are of lower priority than the GUARANTEED containers, that is, they can be preempted for a GUARANTEED container to start its execution.
In YARN-2877, we enabled distributed scheduling in YARN, and OPPORTUNISTIC containers are scheduled exclusively by distributed schedulers.
In this JIRA, we are proposing to extend the centralized YARN RM in order to enable the scheduling of OPPORTUNISTIC containers in a centralized fashion.
