它在本地运行良好。当我试着在映射规约模式中运行pig时，该任务失败了，但是日志没有显示任何错误。

结构如下所示：

export JAVA_HOME=/home/hadoop/jdk1.6.0_39

export HADOOP_HOME=$MY_HOME/hadoop-0.20.2-cdh3u4

export CLASSPATH=$JAVA_HOME/lib/tools.jar:.

export HIVE_HOME=$MY_HOME/hive-0.7.1-cdh3u4

export PIG_HOME=$MY_HOME/pig-0.8.1-cdh3u4

export HBASE_HOME=$MY_HOME/hbase-0.90.6-cdh3u4

export PIG_CLASSPATH=”`${HBASE_HOME}/bin/hbase classpath`:$PIG_CLASSPATH”

我试着在pig_home/lib中注册zookeeper和hbase的jar。

在PIG/lib中注册hbase，zookeeper jar，在hbase lib中注册guava jar。
