[jira] [Commented] (TEZ-2132) Support fault tolerance & speculation in pipelined data transfer for ordered output

    [ https://issues.apache.org/jira/browse/TEZ-2132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15727703#comment-15727703 ] 

Ming Ma commented on TEZ-2132:
------------------------------

[~rajesh.balamohan], any plan to work on it? It appears the issue also applies to unordered output,. For the unordered output case, there is no merge, but the downstream vertex processor can start to consume data as soon as some input is available. The solution for unordered can be different from the ordered. Maybe we can fix them separately. Thanks.
