Subject [jira] [Created] (YARN-7610) Extend Distributed Shell to support launching job with opportunistic containers
Date Tue, 05 Dec 2017 08:22:00 GMT
Weiwei Yang created YARN-7610:
---------------------------------

             Summary: Extend Distributed Shell to support launching job with opportunistic
containers
                 Key: YARN-7610
                 URL: https://issues.apache.org/jira/browse/YARN-7610
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: applications/distributed-shell
            Reporter: Weiwei Yang
            Assignee: Weiwei Yang


Per doc in [https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/OpportunisticContainers.html#Running_a_Sample_Job],
user can run some of PI job mappers as O containers. Similarly, propose to extend distributed
shell to support specifying the container type, it will be very helpful for testing. Propose
to add following argument

{code}
$./bin/yarn org.apache.hadoop.yarn.applications.distributedshell.Client
-container_type <arg>                          Container execution type,
                                                GUARANTEED or
                                                OPPORTUNISTIC
{code}

Implication: all containers in a distributed shell job will be launching as user-specified
container type (except for AM), if not given, default type is {{GUARANTEED}}. AM is always
launched as {{GUARANTEED}} container.
