Subject [jira] [Commented] (REEF-1407) Catching exceptions in group communication in failure case
Date Tue, 31 May 2016 18:14:13 GMT

    [ https://issues.apache.org/jira/browse/REEF-1407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15308262#comment-15308262

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

Regarding first solution with timeout, it is not as simple as stated here. We have pipelining
also, which means that if we timeout in middle of message being sent we are in trouble and
cannot recover currently.

> 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.
