Jobconf should set the default output value class to be Text
------------------------------------------------------------

Key: HADOOP-534
URL: http://issues.apache.org/jira/browse/HADOOP-534
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.6.1
Reporter: Hairong Kuang
Assigned To: Hairong Kuang
Fix For: 0.6.2


When input files are in the text format, the input value class is set to be Text. But the output value class is by default set to be UTF8. This causes the Grep example to fail.
