Ya creé una carga masiva en hbase en un clúster kerberos con una clase de controlador similar a esta (en funcionamiento):

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;
}

Ahora me gustaría implementar la carga masiva segura, pero parece que esto debe implementarse usando el marco de coprocesador (hbase 1.0.0) ¿alguien puede darme un ejemplo completo de cómo usar el método securebulkloadHFiles? Gracias por la ayuda
