["Runping Qi (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-1547?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Runping Qi updated HADOOP-1547:
-------------------------------

    Attachment: patch_1547.txt


This patch addresses the following issues:

1. Move the TestAggregate to mapred.lib.aggregate package.

2. Provide an example in the examples dir. 
The example is to use Aggregate to count the word occurrences in the input files.

3. Replace work Abacus in the comments in the source files with Aggregate

4. Modify the ValueAggregatorJob so that it allows the user to specify a user jar file
in the spec file under attribute anme "user.jar.file". 
This makes Aggregate package work without depending on HADOOP-1521

> As a part of this issue move TestAggregates to the org.apache.hadoop.mapred.lib.aggregate package.
