Subject [jira] [Commented] (REEF-1224) IMRU Fault Tolerance - Separate Data downloading from Task injection
Date Thu, 17 Mar 2016 21:45:33 GMT

    [ https://issues.apache.org/jira/browse/REEF-1224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15200450#comment-15200450

Dhruv Mahajan commented on REEF-1224:
-------------------------------------

What do you mean by each and every context. When we submit context, and if we bind it in configuration
for that context only then it will fire right? Plus if we are putting logic in cosntructor,
it will be invoked only once right? Am I missing something here?

> Currently in IMRU, data downloading happens during the Task injection. It couples the
data and Task object. In Fault tolerant case, we would like to only resubmit a task but use
the data that have been downloaded, That requires us to decouple those two portions. For example,
data downloading portion can be attached to Context, and we can then resubmit a task on the
same context.
