Jeff Zhang commented on TEZ-1633:
---------------------------------
[~apivovarov] Thanks for your finding and patch.
I attach a new patch which invoke "dispatcher.await()" (wait until all the
events is handled by Dispatcher). We should not use Thread.sleep as possible
as we can since it can not guarantee to solve the issue completely. I saw you
create a similar ticket
[TEZ-1632|https://issues.apache.org/jira/browse/TEZ-1632], wondering whether we
could solve the issue same way.
