Hi,
You can use the new api in your action if you set these two properties in
the action's <configuration> section:
<property>
<name>mapred.mapper.new-api</name>
<value>true</value>
</property>
<property>
<name>mapred.reducer.new-api</name>
<value>true</value>
</property>
The JobConf.setUseNewMapper(boolean flag) simply sets the same property;
same with JobConf.setUseNewReducer(boolean flag).
