Hi All,
I install hadoop 2.5.1 on my computer as a single node cluster in
Pseudo-Distributed mode.
I followed the instructions in the web page
'_http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html_'.
It seems all right until I run mapreduce example below:
huan@huan-ThinkPad-T410:~$ hadoop jar
~/hadoop-2.5.1/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.5.1.jar grep
input output 'dfs[a-z.]+'

So please give me a guide of the problem? Thanks a lot.
My configuration as below:
yarn-site.xml:
<configuration>
<!-- Site specific YARN configuration properties -->
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
</configuration>
mapred-site.xml:
<configuration>
<property>
