sqoop export from oracle blob type data into hbase

Research sqoop export data problems, the basic operation have been achieved, but sqoop export from oracle blob type data into hbase when problems get a lot of people say you need to modify jdbc pages of source code, someone encountered this problem? Also forgot to let me know.
------ Solution ---------------------------------------- ----
official explanation seems to be supported through a test page through sqoop into hdfs in the blob, but when imported into hbase has not been successful, expect answers
------ Solution --------------------------------------------
sorry, I did not write on the 1st floor
should sqoop not supported direct blob data to guide the way

explain my approach
give an example of LZ

- created in Oracle Blob field with a data sheet
- temp_01 (idx int, bstr Blob, aaa varchar2 (10))
- insert test data

 insert into temp_01 (idx, bstr, aaa) values ??(1, to_blob ('aaa'), 'aaa'); insert into temp_01 (idx, bstr, aaa) values ??(2, to_blob ('bbb'), 'bbb'); insert into temp_01 (idx, bstr, aaa) values ??(3, to_blob ('ccc'), 'ccc'); insert into temp_01 (idx, bstr, aaa) values ??(4, to_blob ('ddd'), 'ddd'); 
 - Query 
 SELECT t. * FROM temp_01 t 
 
 / ***************** 
 Idx bstr aaa 
 1  aaa 
 2  bbb 
 3  ccc 
 4  ddd 
 ****************** / 
  
 
 perform SQOOP import program to the HDFS directory / tmp/temp01_tmp01 in 
 
 sqoop import - append - connect jdbc: oracle: thin: @ 10.126.24.31:1521: FRDB - username XXX - password XXX - -table temp_01 - columns idx, aaa, bstr - target-dir / tmp/temp01_tmp01-m 1 - inline-lob-limit 16777216  
 
 Here is the output

 comma separated last column is the BLOB data 
 Then how to deal with, LZ can figure it out, mapping HIVE, you can import HBASE 
 
 I did not put BLOB (MYSQL, ORACLE) data directly into too HBASE, HDFS are imported in this manner 
 Then HBASE directory mapping to create the BLOB

 ?This post last edited by the tntzbzc on 2013-05-23 11:30:48  Sqoop's direct mode does not support imports of BLOB, CLOB, or LONGVARBINARY columns. Use JDBC-based imports for these columns; do not supply the - direct argument to the import tool. 
 
 This is sqoop official explanation, sqoop does not support direct way to guide blob data 
 
 Link:  BLOB and CLOB columns

 that I want to export from oracle blob data to hbase, you must use java script support it? Or need to import the data into hdfs, then import hbase? 
 ------ For reference only -------------------------------------- - 
 Incidentally, BLOB directly into HBASE, seemingly not, at least I have not succeeded guide 
 If you have any other users success, please send method to share

 tried it directly into hdfs indeed, this method is possible, but would like to live incremental import data, or not, and then look, thank Bamboo! !

 not use SQOOP real import, and write their own programs Run
