Hi, In recent thread about existing components taking long time to heartbeat after upgrade; it was mentioned that "slider AM restarts itself to pick up Yarn parameters"
If the upgrade simply consist of starting a new component, is the AM restart still needed ? I.e. if the hadoop cluster configuration has not changed and the Yarn parameters in the slider applications have not changed for any components and upgrade is being used just to start a new component; is AM restart still needed ? The use case is for service running large number of components. When a new user is enabled for service, a new component is started for that user. However, no changes are done for hadoop cluster or in the slider application configuration for any existing components. When large number of users (i.e. components) are already running, AM restart means these existing components have to be informed of new AM and vice versa. In such cases, if AM restart is not needed, can it be avoided e.g. by having a new option in Upgrade command ? Thanks, Manoj
