Wangda Tan updated YARN-1609: ----------------------------- Assignee: (was: Wangda Tan) > 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 > Attachments: Add Service Container type to NodeManager in YARN-V1.pdf > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
