在CDH4集群（Hadoop 2 + MapReduce v1）上运行Pig时无法进入mapreduce模式

Question

I want to run pig scripts (non-embedded and embedded) on a CDH4 cluster of 3 Amazon instances. I created a fake configuration file (but the addresses are correct) for pig located at /home/ubuntu/core-site.xml that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <property>
    <name>fs.default.name</name>
    <value>hdfs://server1:8020</value>
  </property>
  <property>
    <name>mapred.job.tracker</name>
    <value>server1:8021</value>
  </property>
</configuration>

When I tried to run:

ubuntu@server1:~$ export HADOOP_CONF_DIR=/home/ubuntu
ubuntu@server1:~$ export PIG_CLASSPATH=/home/ubuntu
ubuntu@server1:~$ pig -x mapreduce -f test.pig 

The script ran and returned correct result but in the console I found a lot of "LocalJobRunner" and in MapReduce job tracker web interface no job is reported. Can any one tell me why doesn't it run in mapreduce mode and why doesn't it report any error of that situation? How can I run it in mapreduce mode?

My cluster is 4.1.3 (freshly installed, all configuration is default) with Pig 0.10.0-cdh4.1.3.
