hadoop - 从HDFS加载数据并使用Pig写入HBase时出错

Question

如何将hdfs中的mapreduce程序的输出数据加载到hbase中？

我试图运行以下Pig命令将数据从hdfs加载到hbase:-

A = LOAD 'hdfs://b**/user/user1/development/hbase/output/part-00000' USING PigStorage('t') as (strdata1:chararray, strdata2:chararray); 
STORE A INTO 'hbase://mydata' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('mycf:strdata2');

其中， hdfs://b**/user/user1/development/hbase/output/part-00000是map-reduce输出 mydata是创建的hbase表名称 mycf是列族名称

我收到以下错误:

只能从数据源字符串中删除hbase://模式:
使用org.apache.pig.backend.hadoop.hbase.HBaseStorage('mycf:strdata2')存储到“mydata”中；
