how to ignore first two bytes hdfs writeUTF and writeChars?

Question

I have written some data in hdfs, but i want that to be without the first two bytes that the writeUTF() method writes. I want to copy this first two byte free hdfs file to local file and do some analysis on it.

if (fs.exists(filenamePath)) {
        // remove the file first
        //fs.delete(filenamePath);
         out = fs.append(filenamePath);
    }
    // create if file doesnt exists
    else{
        out = fs.create(filenamePath);
    }

    out.writeUTF(getFeaturesString(searchCriteriaList,fileNameData));
    out.close();

The data written is as follows

0aEX Series ex4200-24f....

I want only

EX Series   ex4200-24f  

I write all the data to hdfs file and then I am copying the file into local to do some analysis. Is there an alternative method to accomplish this..

how to ignore first two bytes hdfs writeUTF() and writeChars() ?

You've just answered your own question. Use writeChars() .

writeUTF() is only useful when somebody is going to be calling readUTF() to read it. It uses a modified character set and a length-word that is only understood by readUTF() .

There's no particular reason to use DataOutputStream here either. If the data is all text, use a BufferedWriter.
