No-sort optimization
--------------------
Key: HADOOP-939
URL: https://issues.apache.org/jira/browse/HADOOP-939
Project: Hadoop
Issue Type: New Feature
Components: mapred
Environment: all
Reporter: Doug Judd
There should be a way to tell the mapred framework that the output of the map()
phase will already be sorted. The Reduce phase can just merge the intermediate
files together without sorting.
