[jira] [Commented] (TEZ-2581) Umbrella for Tez Recovery Redesign

    [ https://issues.apache.org/jira/browse/TEZ-2581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14984639#comment-14984639 ] 

Jeff Zhang commented on TEZ-2581:
---------------------------------

The vertex/vertexgroup may still have downstream vertices. So if its full recovery events are not seen, its downstream vertices can not get the DM events. And we also can not rerun the vertex, since the committing has been done.
