Subject [jira] [Commented] (YARN-8160) Yarn Service Upgrade: Support upgrade of service that use docker containers
Date Fri, 13 Apr 2018 22:09:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-8160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16438000#comment-16438000
] 

Eric Yang commented on YARN-8160:
---------------------------------

Base on what I read from YARN-7973, the relaunch event is encapsulated in ContainerLauncher.  By
passing parameter to ContainerLauncher event, it can trigger relaunch of container to happen.  Where
YARN-7939 code have added a new transition for relaunch in ContainerImpl, and trigger a new
type of relaunch event.  The alignment can happen if we surface YARN-7973 logic from ContainerLauncher
and connect with the new transition event for doRelaunch.  It might help to refine relaunch
logic and reuse some of the existing code.
