Allow shuffle read and connection timeouts to be configurable
-------------------------------------------------------------

                 Key: HADOOP-5789
                 URL: https://issues.apache.org/jira/browse/HADOOP-5789
             Project: Hadoop Core
          Issue Type: Improvement
          Components: mapred
    Affects Versions: 0.20.0
            Reporter: Arun C Murthy
            Assignee: Arun C Murthy
             Fix For: 0.21.0


It would be good for latency-sensitive applications to tune the shuffle read/connection timeouts...
in fact this made a huge difference to terasort since we were seeing individual shuffles stuck
for upwards of 60s and had to have a very small read timeout.
