Hi Guys, I created a feature request for YARN. Any comments/suggestions on that?
https://issues.apache.org/jira/browse/YARN-2518 Support in-process container executor Node Manage always creates a new process for a new application. We have hit a scenario where we want the node manager to execute the application inside its own process, so we get fast response time. It would be nice if Node Manager or YARN can provide native support for that. In general, the scenario is that we have a long running process which can accept requests and process the requests inside its own process. Since YARN is good at scheduling jobs, we want to use YARN to dispatch jobs (e.g. requests in JSON) to the long running process. In that case, we do not want YARN container to spin up a new process for each request. Instead, we want YARN container to send the request to the long running process for further processing. Thanks, Bo
