Subject [jira] [Updated] (REEF-1733) Adding a method in IUpdateFunction to return TaskProgress
Date Fri, 17 Feb 2017 18:39:41 GMT

     [ https://issues.apache.org/jira/browse/REEF-1733?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Julia updated REEF-1733:
------------------------
    Description: 
This is to define IDriverMetrics and a simple implementation. MetriceService will be an observer
of the driver metrics. 




  was:
This is to add an {{ITaskProgressReporter}} interface to return the current progress of the
task. It can be implemented by update task functions and {{UpdateTaskHost}} can then get the
task progress by calling this API. 

{{TaskProgress TaskCurrentProgress();}}

{{TaskProgress}} will contain iteration number, progress, etc. We can put minimum properties
for now and extend it when needed. 

As mappers' data are aggregated in update task, update task function is the one that knows
the task progress and iterations, getting task progress from update task function should be
sufficient for now.
