Subject [jira] [Commented] (REEF-1407) Catching exceptions in group communication in failure case
Date Wed, 01 Jun 2016 00:43:12 GMT

    [ https://issues.apache.org/jira/browse/REEF-1407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15308971#comment-15308971
] 

Dhruv Mahajan commented on REEF-1407:
-------------------------------------

So we register IObservers with Transport Servers and Clients. If Servers and Clients are closing
they can potentially push error messages in these observers which are then received and processed
by group communication accordingly. To me this seems like an elegant solution with no loopholes.
[~markus.weimer] [~juliaw] what do you think?

> 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.
