[jira] Created: (HADOOP-5789) Allow shuffle read and connection
timeouts to be configurable
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.
