Subject [jira] [Commented] (REEF-1565) Make Context accessible from task
Date Fri, 16 Sep 2016 22:38:20 GMT

    [ https://issues.apache.org/jira/browse/REEF-1565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15497610#comment-15497610
] 

Markus Weimer commented on REEF-1565:
-------------------------------------

Wouldn't it be more natural to fix the REEF.NET Evaluator to properly use Tang in the way
the java version does? That way, the Context can contain an injectable object which is made
available to the Task, instead of exposing implementation details to the user like the PR
for this does.

> For fault tolerant, states should be saved at context level so that when the task is
resubmitted, update task host would be able to restore the state from the context. 
> Currently, we start task from context. But inside task we are not able to access context.
As ContextRuntime could have multiple instances, it is not created by injection. 
> This Jira is to make Task able to inject context where the task is running on. This is
the first step for the state management.
