HBASE通过bulkload方式将文件导入到HBASE数据库2

//--------------第0步导出ORACLE表到HDFS------------
bin/sqoop import \

--target-dir /user/beifeng/sqooporacletohdfscore \

//---------------------第一步把文件转换为hfile 本例是把importtsv文件下的数据文件输出到hfileoutput转换成hfile-----------------------------------------------------------------------
