Varun Saxena reassigned YARN-3417: ---------------------------------- Assignee: Varun Saxena > AM to be able to exit with a request saying "restart me with these (possibly > updated) resource requirements) > ------------------------------------------------------------------------------------------------------------ > > Key: YARN-3417 > URL: https://issues.apache.org/jira/browse/YARN-3417 > Project: Hadoop YARN > Issue Type: New Feature > Components: resourcemanager > Affects Versions: 2.7.0 > Reporter: Steve Loughran > Assignee: Varun Saxena > Priority: Minor > > If an AM wants to reconfigure itself or restart with new resources, there's > no way to do this without the active participation of a client. > It can call System.exit and rely on YARN to restart it -but that counts as a > failure and may lose the entire app. furthermore, that doesn't allow the AM > to resize itself. > A simple exit-code to be interpreted as restart-without-failure could handle > the first case; an explicit call to indicate restart, including potentially > new resource/label requirements, could be more reliabile, and certainly more > flexible. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
