[jira] [Commented] (TEZ-1588) Stop modifying the DAG during createDAG() compilation

["Bikas Saha (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TEZ-1588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14135980#comment-14135980 ] 

Bikas Saha commented on TEZ-1588:
---------------------------------

This is related to TEZ-1563. The fix in there was a safe one for 0.5.1. Attaching a more involved fix here that does not modify the DAG during compilation. Also this fix is better because the notion of DAG common resources is retained by the DAG and can be used for newly added vertices at runtime (when vertex addition becomes supported). The test added in TEZ-1563 continues to work. Other tests modified and added to account for this change. Since this is more involved we could leave it for 0.6 or consider it for 0.5. [~jeagles] Please review.
