Subject [jira] [Commented] (REEF-1407) Catching exceptions in group communication in failure case
Date Mon, 06 Jun 2016 23:03:21 GMT

    [ https://issues.apache.org/jira/browse/REEF-1407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15317454#comment-15317454
] 

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

This will make sure that error will be received on the current or subsequent group comm. call.
For example, node 0 might be successful in sending messages to node 1 but 1 might fail after
that. Now, 0 will receive error on subsequent calls since all connections will eventually
be closed since we are shutting down the whole group communication.

> 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.
