Jeff Zhang commented on TEZ-1689:
---------------------------------
[~sseth] I attach one initial patch which only cover the exception handling of
EdgemanagerPlugin. The exception from InputInitializer.initialize is already
caught, it would lead RootInputInitFailed, the exception from other API of
InputIntializer are not easy to caught. They are not in the state machine
transition.
For the exception in EdgeManagerPlugin API is all caught and unit test is
added, but some places may still need to refine. Please help review it.

> exception, we should handle it, fail the DAG and display the exception in
> client side.
