PIG:ERROR 1000:解析时出错

Question

我在我的机器上安装了Pig 0.12.我跑的时候

darwin$ pig
grunt> ls /data/
hdfs://Nmame:10001/data/pg20417.txt<r 3>    674570
hdfs://Nname:10001/data/pg4300.txt<r 3> 1573150
hdfs:/Nname:10001/data/pg5000.txt<r 3>  1423803
hdfs://Nname:10001/data/weather <dir>

但是当我尝试创建查询时,出现以下错误:

grunt> book = load '/data/pg4300.txt' as (lines:chararray);
2014-06-30 17:40:08,939 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1000: Error during parsing. Encountered " <PATH> "book=load "" at line 2, column 1.

我试图改变load到LOAD和as到AS,但毫无效果.

Answer 1

我遇到了同样的问题,正在寻找解决方案.事实证明,如果你不给空间,就会发生这种情况.book=load会给你一个错误.book = load将工作.我不确定这是否是预期的行为.

Answer 2

尝试以下解决方案，它应该有效 -

1) 删除 /data/ 如果您的数据存在于 HDFS 默认目录中，则无需使用绝对路径。我假设 /data 是您存储所有数据的默认目录 -

book = load 'pg4300.txt' as (lines:chararray);

2）尝试使用PigStorage指定分隔符。我在这里使用逗号作为分隔符，您可以将其替换为您正在使用的分隔符 -

book = load 'pg4300.txt' using PigStorage(',') as (lines:chararray);

希望这可以帮助。
