当我尝试将数据从 hdfs 复制到 hbase uisng pig 时，输入文件中有两个以上的列（或字段）。我收到错误。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：create '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工作正常。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');
