title: How to load data into hbase
body: <p>I would like to load data into Hbase so I tried to a simple example from book HBASE: Definitive guide.
  HbaseHelper.java was loaded.</p>
  
  <pre><code>import org.apache.hadoop.conf.Configuration;
  import org.apache.hadoop.hbase.HBaseConfiguration;
  import org.apache.hadoop.hbase.client.HTable;
  import org.apache.hadoop.hbase.client.Put;
  import org.apache.hadoop.hbase.util.Bytes;
  // ^^ PutExample
  import util.HBaseHelper; 
  // vv PutExample
  
  import java.io.IOException;
  
  public class PutExample {
  
    public static void main(String[] args) throws IOException {
      Configuration conf = HBaseConfiguration.create(); // co PutExample-1-CreateConf Create the required configuration.
  
      // ^^ PutExample
      HBaseHelper helper = HBaseHelper.getHelper(conf);
      helper.dropTable("testtable1");
      helper.createTable("testtable1", "colfam1");
      // vv PutExample
      HTable table = new HTable(conf, "testtable1"); // co PutExample-2-NewTable Instantiate a new client.
  
      Put put = new Put(Bytes.toBytes("row1")); // co PutExample-3-NewPut Create put with specific row.
  
      put.add(Bytes.toBytes("colfam1"), Bytes.toBytes("qual1"),
        Bytes.toBytes("val1")); // co PutExample-4-AddCol1 Add a column, whose name is "colfam1:qual1", to the put.
      put.add(Bytes.toBytes("colfam1"), Bytes.toBytes("qual2"),
        Bytes.toBytes("val2")); // co PutExample-4-AddCol2 Add another column, whose name is "colfam1:qual2", to the put.
  
      table.put(put); // co PutExample-5-DoPut Store row with column into the HBase table.
    }
  }

  <p>I did javac -classpath hbase-version.jar:hadoop.jar:zookeeper.jar:log4j.jar:commons-logging.jar:commons-lang.jar PutData.java (they are in a same directory) but it cannot be complied successfully. 
  It is said:</p>
  
  <pre><code>Note: Some input files use or override a deprecated API.
  Note: Recompile with -Xlint:deprecation for details.
  Note: Some input files use unchecked or unsafe operations.
  Note: Recompile with -Xlint:unchecked for details.

  <p>I tried some other similar method to put data. The errors are same. How can I do it in any possible way?</p>
