Pig 0.7.0 错误 2118:无法在 Hadoop 1.2.1 上创建输入拆分 [英] Pig 0.7.0 ERROR 2118: Unable to create input splits on Hadoop 1.2.1

问题描述

我从 map reduce 程序得到了输出文件(存储在 HDFS 上).现在我正在尝试使用 PIG 0.7.0 加载该文件.

I got output file(stored on HDFS) from map reduce program. now I am trying to load that file using PIG 0.7.0.

我收到以下错误.我试过将此文件复制到本地机器并在本地模式下运行 pig ，效果很好.但我想跳过这一步，让它在地图缩减模式下工作.

I am getting following error. I have tried copying this file to local machine and ran pig in local mode which works fine. but I want to skip this step and make it work from map reduce mode.

我尝试过的选项:

LOAD 'file://log/part-00000', 
LOAD '/log/part-00000', 
LOAD 'hdfs:/log/part-00000', 
LOAD 'hdfs://localhost:50070/log/part-00000', 

<小时>

hadoop dfs -ls /log/

pig(在 mapreduce 模式下运行)

pig (running in mapreduce mode)

grunt> REC = LOAD 'file://log/part-00000' as (CREATE_TMSTP:chararray,         MESSAGE_TYPE:chararray, MESSAGE_FROM:chararray, MESSAGE_TEXT:chararray);
grunt> DUMP REC;

推荐答案

您应该尝试升级到更新版本的 Pig.0.7.0 已经有好几年了.0.12.0 是当前的稳定版本.

You should try upgrading to a more recent version of Pig. 0.7.0 is quite a few years old. 0.12.0 is the current stable release.
