[jira] [Commented] (TEZ-2439) Should not throw exception in
DAGClientHandler#getVertexStatus when DAG is not initialized
[ https://issues.apache.org/jira/browse/TEZ-2439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15440012#comment-15440012 ]
Hitesh Shah commented on TEZ-2439:
----------------------------------
Comment: it seems like this will return a valid status even for an actually non existent vertex as the dag does not check the plan to see if the vertex name is valid?
