代码样例

以下代码片段在com.huawei.bigdata.hbase.examples包的“HBaseSample”类的testDelete方法中。

public void testDelete() {    LOG.info("Entering testDelete.");    byte[] rowKey = Bytes.toBytes("012005000201");    Table table = null;    try {      // Instantiate an HTable object.      table = conn.getTable(tableName);      // Instantiate an Delete object.      Delete delete = new Delete(rowKey);      // Submit a delete request.      table.delete(delete);      LOG.info("Delete table successfully.");    } catch (IOException e) {      LOG.error("Delete table failed " ,e);    } finally {      if (table != null) {        try {          // Close the HTable object.          table.close();        } catch (IOException e) {          LOG.error("Close table failed " ,e);        }      }    }    LOG.info("Exiting testDelete.");  }
