Remove all use of auto-progress threads in map/reduce
-----------------------------------------------------
Key: HADOOP-1488
URL: https://issues.apache.org/jira/browse/HADOOP-1488
Project: Hadoop
Issue Type: Bug
Components: mapred
Reporter: Owen O'Malley
During the last rework of the shuffle, a lot of the stages of the shuffle had
auto-progress threads added, leading to system lockups when the shuffle stalls.
We need to add Progressables to the sort and fetching interfaces so that if any
task gets stuck, it will eventually be killed by the framework.
