-----------------------------------
Hi [~kkaranasos]
Could you please help to review? Checkstyle issues were complaining about the
init method exceeds 150 lines, which is not introduced by this patch. Thanks.
> 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
> Attachments: YARN-7610.001.patch
>
>
> 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.
