[jira] [Commented] (TEZ-2745) ClassNotFoundException of user code should fail dag

    [ https://issues.apache.org/jira/browse/TEZ-2745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14726792#comment-14726792 ] 

Hitesh Shah commented on TEZ-2745:
----------------------------------

General comment:
  - from a quick look at the patch, I dont see any public apis needing to change to add a "throws TezException" - can you confirm?
  - could we introduce a specialized derived class of TezException for instance creation exception instead of overloading TezException?

> This ClassNotFoundException is not captured now. The current behavior is AM crashed and relaunched again until max app attempt is reached. 
> Here's user code used in AM:
> * EdgeManager
> * VertexManager
> * InputInitializer
> * OutputCommitter
> * Other user pluggable components (like DAGScheduler, HistoryServiceLogging etc.)
