我从map reduce程序获得了输出文件（存储在HDFS上）。现在我正在尝试使用PIG 0.7.0加载该文件。
我收到了以下错误。我试过将这个文件复制到本地机器并在本地模式下运行猪，这很好。但我想跳过这一步，让它从map reduce模式开始工作。
我试过的选项：
LOAD 'file://log/part-00000',
LOAD '/log/part-00000',
LOAD 'hdfs:/log/part-00000',
LOAD 'hdfs://localhost:50070/log/part-00000',
hadoop dfs -ls /log/
Warning: $HADOOP_HOME is deprecated.
Found 3 items
-rw-r--r-- 3 supergroup 0 2014-02-07 07:56 /log/_SUCCESS
drwxr-xr-x - supergroup 0 2014-02-07 07:55 /log/_logs
-rw-r--r-- 3 supergroup 10021 2014-02-07 07:56 /log/part-00000
pig（以mapreduce模式运行）
grunt> REC = LOAD 'file://log/part-00000' as (CREATE_TMSTP:chararray, MESSAGE_TYPE:chararray, MESSAGE_FROM:chararray, MESSAGE_TEXT:chararray);
grunt> DUMP REC;

答案 0 :(得分：1)
您应该尝试升级到更新版本的Pig。 0.7.0已经有几年了。 0.12.0是当前的稳定版本。
