Question

当我尝试将数据从hdfs复制到输入文件中有两列以上（或字段）的hbase uisng pig时。我收到了错误。详细示例：

HDFS中的

文件：/home/1.txt

1   2   3   4
5   6   7   8

具有两个列族的Hbase表：创建'table1'，'P'，'S'

猪命令：

A= load '/home/1.txt' using PigStorage('\t') as (one:chararray,two:chararray,three:chararray,four:chararray);

STORE A INTO 'hbase://table1' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('P:one,P:two,S:three,S:four');

错误日志：

但是当我尝试只复制两个字段时，它可以正常工作。下面的代码：

A= load '/home/1.txt' using PigStorage('\t') as (one:chararray,two:chararray);

STORE A INTO 'hbase://table1' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('P:one,P:two,S:three,S:four');



[s@namenode ~]$ hadoop version
Hadoop 0.20.2-cdh3u6
Hbase version : Version 0.90.6-cdh3u6
Pig version:  Apache Pig version 0.8.1-cdh3u6 (rexported)

Answer 1

A = LOAD＆＃39; /home/1.txt'使用PigStorage（＆＃39;，＆＃39;）为（id：int，name：chararray，city：chararray）;

使用pig从hdfs到hbase的数据传输
