----------------------------------------------------------
[~jeagles], Request for review. The patch makes changes to how
InputAttemptIdentfiers are processed and removed for local as well as http
fetch in unordered case. The hang stems from the case where auto reduction is
on and the first partition of the composite fetch is empty. Thanks!
