Subject [jira] [Commented] (REEF-1378) Evaluator Manager for IMRU
Date Tue, 03 May 2016 18:45:13 GMT

    [ https://issues.apache.org/jira/browse/REEF-1378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15269331#comment-15269331

Julia commented on REEF-1378:
-----------------------------

You are talking about current IMRU case, one evaluator only has one root context. What I talked
about is in general one evaluator may have multiple active contexts. And in future, we might
only need to resubmit a context instead of entire evaluator. When we design a system, we should
make it extensible for next phase. 
Basically we need to keep failed evaluators and total allocated evalautors to control the
state change and determine what and how many evaluators need to recover in any phase not just
before contexts are created.
