Subject [jira] [Commented] (YARN-1318) Promote AdminService to an Always-On service
Date Mon, 28 Oct 2013 17:20:31 GMT

    [ https://issues.apache.org/jira/browse/YARN-1318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13806949#comment-13806949

----------------------------------------

Thanks for chipping in, Vinod. 

bq. The current method of passing in whatever is possible in constructor and set the remaining
using setters when they are ready should continue to work. Why do we need to change it?
If AdminService moves to Always-On service, even the RMContext needs to be created before
AdminService. None of the ActiveServices are created yet by that point, and hence the need
for that change.

> Per discussion in YARN-1068, we want AdminService to handle HA-admin operations in addition
to the regular non-HA admin operations. To facilitate this, we need to move AdminService an
Always-On service.
