Devaraj Das commented on HADOOP-1337:
-------------------------------------

Made this a minor issue since the shuffle code does not have known issues as-of-date. However, the DFA probably is the ideal model to go after.

> The shuffle code (for fetching map outputs) should proceed as a DFA. The states (as Owen had mentioned on HADOOP-1183) are (INITIAL, LOCATED, FETCHING, DONE, FAILED). This is to ensure correctness of map output fetching.
