Date Thu, 23 Oct 2014 09:53:33 GMT

Jeff Zhang commented on TEZ-1267:

[~bikassaha] Thanks for your comment.  You are right, Wrap into a common method would be better,
but it may need some code structure change, involves some risk, do it in 0.6 may be better.

> Events are generated by user code. In some places they're also handled by user code within
the AM. Currently, exceptions which are generated when handling user code will end up killing
the AM (and hence leading to a retry).
> Instead, failure to handle such events, should cause the application to fail.
