Subject [jira] [Commented] (REEF-1407) Catching exceptions in group communication are implemented incorrectly
Date Mon, 13 Jun 2016 06:36:20 GMT

    [ https://issues.apache.org/jira/browse/REEF-1407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15326890#comment-15326890
] 

Julia commented on REEF-1407:
-----------------------------

Are you taking about OnError or OnComplete or both? 

For OnError, can we create an exception type and wraps the client's end point information
in it? 
For OnComplete, there is no parameter. Can we use a special message for completion?

> Currently when a task fails, other tasks in the group are stuck in reading data by a
blocking call. We should be able to try and throw an exception and propagate the exception
to Task so that the task can handle it in a proper way.
