Shuffle connection logic needs correction
------------------------------------------
Key: MAPREDUCE-1276
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1276
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: task
Affects Versions: 0.21.0
Reporter: Jothi Padmanabhan
Assignee: Amareshwari Sriramadasu
Priority: Blocker
Fix For: 0.21.0
While looking at the code with Amareshwari, we realized that
{{Fetcher#copyFromHost}} marks connection as successful when
{{url.openConnection}} returns. This is wrong. Connection is done inside
implicitly inside {{getInputStream}}; we need to split {{getInputStream}} into
{{connect}} and {{getInputStream}} to handle the connection and read time out
strategies correctly.
