Subject [jira] [Created] (REEF-1507) IMap and IUpdate tasks should be initialized in the *Host constructors
Date Thu, 04 Aug 2016 19:47:20 GMT
Dhruv Mahajan created REEF-1507:
-----------------------------------

             Summary: IMap and IUpdate tasks should be initialized in the *Host constructors
                 Key: REEF-1507
                 URL: https://issues.apache.org/jira/browse/REEF-1507
             Project: REEF
          Issue Type: Improvement
          Components: REEF.NET
         Environment: C#
            Reporter: Dhruv Mahajan
            Assignee: Dhruv Mahajan


Currently in IMRU, {{IMapTask}} and {{IUpdateTask}} are injected as part of constructor of
corresponding {{*Host}} Tasks. As a result currently, when we ask for group comm. operators
and registration happens, first we have to wait fpr data to be downloaded, since it is typically
accessed within the constructor of {{IMapTask}}. As a result master task can timeout in registration
and retry parameter there needs to change depending on the size of data. 

We would like to delay the initiation of {{IMapTask}} by getting the injector in the task
creation and only initiating the map and master tasks at the end of the constructor.
