Já criei uma carga em massa no hbase em um cluster kerberos com uma classe de driver semelhante a esta (funcionando):

public static void main(String[] args) {        
    try {
        int response = ToolRunner.run(HBaseConfiguration.create(), new HBaseBulkLoadDriver(), args);            
        if(response == 0) {             
            System.out.println("Job is successfully completed...");
        } else {
            System.out.println("Job failed...");
        }
    } catch(Exception exception) {
        exception.printStackTrace();
    }
}

@Override
public int run(String[] args) throws Exception {
    int result=0;

    final String inputPath = args[0];   
    final String outputPath = args[1];      
    final String keytab = args[2];  

    Configuration configuration = getConf();        


    configuration.set("data.seperator", DATA_SEPERATOR);        
    configuration.set("hbase.table.name",TABLE_NAME);
   // configuration.set("INTRO",COLUMN_FAMILY_INTRO);
    configuration.set("hbase.zookeeper.quorum","zk_quorum");
    configuration.set("hbase.zookeeper.property.clientPort","2181");
    configuration.set("hbase.master","master:port");
    configuration.set("hadoop.security.authentication", "Kerberos");
    configuration.set("hbase.security.authentication", "kerberos");

        //configuration.set("COLUMN_FAMILY_2",COLUMN_FAMILY_2);     
    Job job = new Job(configuration);       
    // job configuration
    job.setJarByClass(HBaseBulkLoadDriver.class);       
    job.setJobName("Bulk Loading HBase Table:"+TABLE_NAME);     
    job.setInputFormatClass(TextInputFormat.class);     
    job.setMapOutputKeyClass(ImmutableBytesWritable.class); 
    //mapper class
    job.setMapperClass(HBaseBulkLoadMapper.class);      
    FileInputFormat.addInputPaths(job,inputPath);   
    FileSystem.getLocal(getConf()).delete(new Path(outputPath), true);      
    FileOutputFormat.setOutputPath(job, new Path(outputPath));      
    job.setMapOutputValueClass(Put.class);      
    HFileOutputFormat.configureIncrementalLoad(job, new HTable(configuration,TABLE_NAME));  

    job.waitForCompletion(true);         

    System.out.println("Output written to folder :" + outputPath);

    System.out.println("To proceed loading files user: hbase:hbase must own recursivly the folder!");

    System.out.println("Is hbase user owing the folder?press Y to load the data , press N and job will fail");

    String IsHbaseOwnerOftheFolder = System.console().readLine();

    if (job.isSuccessful() && IsHbaseOwnerOftheFolder.equals("Y")) {
        HBaseBulkLoad.doBulkLoad(outputPath, keytab, TABLE_NAME);
    } else {
        result = -1;
    }
    return result;
}

Agora eu gostaria de implementar o carregamento em massa seguro, mas parece que isso deve ser implementado usando a estrutura do coprocessador (hbase 1.0.0). Alguém pode me dar um exemplo completo de como usar o método securebulkloadHFiles? Obrigado pela ajuda
