Subject [jira] [Updated] (YARN-5220) Scheduling of OPPORTUNISTIC containers through YARN RM
Date Wed, 08 Jun 2016 22:29:21 GMT

     [ 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.
