--------------------------------
Summary: Add Service Container type to NodeManager in YARN
Key: YARN-1609
URL: https://issues.apache.org/jira/browse/YARN-1609
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager
Affects Versions: 2.2.0
Reporter: Wangda Tan
Assignee: Wangda Tan
>From our work to support running OpenMPI on YARN (MAPREDUCE-2911), we found
>that it’s important to have framework specific daemon process manage the tasks
>on each node directly. The daemon process, most likely similar in other
>frameworks as well, provides critical services to tasks running on that
>node(for example “wireup”, spawn user process in large numbers at once etc).
>In YARN, it’s hard, if not possible, to have the those processes to be managed
>by YARN.
We propose to extend the container model on NodeManager side to support
“Service Container” to run/manage such framework daemon/services process. We
believe this is very useful to other application framework developers as well.
