如何将数据从hdfs加载到hbase？

如何将hdfs中的mapreduce程序的输出数据加载到hbase中？如何将数据从hdfs加载到hbase？

我试图运行以下猪命令从HDFS将数据加载到HBase的： -

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是地图，减少输出mydata是创建 mycf HBase的表名是列姓

我收到以下错误： -
