---------------------------------
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.
