我想在包含3個Amazon實例的CDH4集羣上運行豬腳本（非嵌入式和嵌入式）。我創建了一個假的配置文件（但地址是正確的），對位於/home/ubuntu/core-site.xml豬，看起來像這樣：在CDH4集羣上運行Pig時無法進入mapreduce模式（Hadoop 2 + MapReduce v1）
<?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>
當我試圖運行：
[email protected]:~$ export HADOOP_CONF_DIR=/home/ubuntu
[email protected]:~$ export PIG_CLASSPATH=/home/ubuntu
[email protected]:~$ pig -x mapreduce -f test.pig
該腳本運行並返回正確的結果，但在控制檯中，我發現很多「LocalJobRunner」，並且在MapReduce作業跟蹤器Web界面中沒有任何作業被報告。任何人都可以告訴我爲什麼它不在mapreduce模式下運行，爲什麼它不報告這種情況的任何錯誤？我如何在mapreduce模式下運行它？
對於Pig 0.10.0-cdh4.1.3，我的集羣是4.1.3（新安裝，所有配置都是默認配置）。
