文件内容：

one,1
two,2
three,3

文件位置：hdfs:/hbasetest.txt
hbase中的表：

create 'mydata', 'mycf'

Pig脚本：

A = LOAD '/hbasetest.txt' USING PigStorage(',') as (strdata:chararray, intdata:long);
STORE A INTO 'hbase://mydata'
        USING org.apache.pig.backend.hadoop.hbase.HBaseStorage(
              'mycf:intdata');

我得到以下错误：

如果我使用dump命令，它会在grunt上显示文件内容。如何纠正这个问题？？
