Steve Loughran created YARN-3418: ------------------------------------ Summary: AM to be able to set/update web URL and IPC ports post-registration Key: YARN-3418 URL: https://issues.apache.org/jira/browse/YARN-3418 Project: Hadoop YARN Issue Type: Improvement Components: resourcemanager Affects Versions: 2.8.0 Reporter: Steve Loughran
Currently the AM can only set the IPC and HTTP(s) ports on AM registration. This # creates a possible race condition: the IPC and HTTP ports need to come up before the app is fully initialised. This is particularly true on work-preserving AM restarts, as the AM will depend on the list of containers supplied during registration to build its internal state. # prevents the AM from changing these values dynamically during application execution. This matters if the Web or IPC services are hosted not in the AM, but in a deployed container. If the container is restarted, there's no way to rebind the services. A new AM-RM IPC call to publish updated binding information is needed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
