title: Re-parsing Blob data stored in HDFS imported from Oracle by Sqoop
body: <p>Using Sqoop I’ve successfully imported a few rows from a table that has a BLOB column.Now the part-m-00000 file contains all the records along with BLOB field as CSV.</p>
  
  <p>Questions:</p>
  
  <p>1) As per doc, knowledge about the Sqoop-specific format can help to read those blob records. 
  So , What does the Sqoop-specific format means ?</p>
  
  <p>2) Basically the blob file is .gz file of a text file containing some float data in it. These .gz file is stored in Oracle DB as blob and imported into HDFS  using Sqoop. So how could I be able to get back those float data from HDFS file. 
  Any sample code will of very great use.  </p>
