Siddharth Seth updated TEZ-2669:
--------------------------------
Attachment: TEZ-2669.1.txt
First iteration of the patch. Worked on by [~hitesh] and me.
The plugin managers take care of handling exceptions from user code and
shutting down the AM. The itnerfaces itself do not throw Exceptions - I don't
think it's useful doing that since Tez can't take any useful action in such
cases. This also forces the user code to look at possible Exceptions instead of
just letting them filter through to the framework.
A bunch of tests added to verify behaviour.
I think there's some cases - where the framework could have a bug - which can
still cause the AM to restart - i.e. the error reaches the Dispatcher directly.
I'm going to create a separate jira for these.
