Input Format implementation : here 

Design

• If "AbstractFieldValue"(JRecord) type is binary, the data will be encoded to Base64 format.
  

  Integer.parseInt(new String(Base64.decodeBase64(Base64.encodeBase64(value.asString().getBytes()))), 2);

  or

  Base64.decodeInteger(Base64.encodeInteger(value.asBigInteger()));

...

"binaryFilePath": "file:///home/cdap/DTAR020_FB.bin",

"maxSplitSize": "5"

}
