---------------------------------------
This fix will create problems when we run the vaidya scrpit in
hadoop-2.0.0-mr1-cdh4.1.2.

In the job conf file
the properties are like
<property><name>mapred.reduce.slowstart.completed.maps</name><value>0.05</value><source>mapred-default.xml</source><source>/tmp/hadoop-527022/mapred/local/jobTracker/job_201302121643_0003.xml</source></property>
<property><name>io.sort.record.percent</name><value>0.05</value><source>mapred-default.xml</source><source>/tmp/hadoop-527022/mapred/local/jobTracker/job_201302121643_0003.xml</source></property>
<property><name>io.sort.spill.percent</name><value>0.80</value><source>mapred-default.xml</source><source>/tmp/hadoop-527022/mapred/local/jobTracker/job_201302121643_0003.xml</source></property>
all the above lines throw the exception.
The important thing is default values for the above properties are 0.05 and 0.8
> Configuration getInt, getLong, and getFloat replace invalid numbers with the
> default value
