Subject [jira] [Commented] (HIVE-16460) In the console output, show vertex list in topological order instead of an alphabetical sort
Date Thu, 01 Jun 2017 21:31:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16460?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16033732#comment-16033732
] 

Siddharth Seth commented on HIVE-16460:
---------------------------------------

Is baseWork topo sorted? Does each BaseWork instance always correspond to a Vertex in Tez
(I'm not sure this is the case. e.g. Unions). Adding a check to ensure that the BaseWork exists
in the Vertex information returned by Tez will be useful.
If I'm not mistaken, removing the sort in the existing code would be sufficient, and Tez will
return the vertices in a topological sorted order. Can't really rely on this though, since
it's not part of the API spec.
