Subject [jira] [Commented] (REEF-1407) Catching exceptions in group communication in failure case
Date Wed, 01 Jun 2016 00:20:12 GMT

    [ https://issues.apache.org/jira/browse/REEF-1407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15308943#comment-15308943
] 

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

Cancellation token applies to a separate thread, but we are in the blocking call, and we depend
on this blocking call to get messages. 
If we depend on a special message, before the other side receives the message, the communication
might have been disconnected. There is no way to receive that special message.

> 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.
