1.Hbase获取连接：

public class HbaseConnection {private static Configuration config;private static HConnection hconn;private static final Logger LOGGER = LoggerFactory.getLogger(HbaseConnection.class);public static synchronized Configuration getConfiguration() {if (config == null) {try {config = HBaseConfiguration.create();config.set("hbase.zookeeper.property.clientPort",Constants.HBASE_PORT);config.set("hbase.zookeeper.quorum", Constants.HBASE_IPADDRESS);// config.set("hbase.master", Constants.HBASE_MASTER);config.set("hbase.client.retries.number", "1");} catch (Exception e) {e.printStackTrace();LOGGER.error("init HBaseConfiguration error ... "+ e.getMessage());}}return config;}public static synchronized HConnection getHConnection() {if (hconn == null) {try {hconn = HConnectionManager.createConnection(getConfiguration());} catch (IOException e) {e.printStackTrace();LOGGER.error("init HConnection error ... " + e.getMessage());}}return hconn;}}

2.示例：

        HTableInterface table = null;        try {table = HbaseConnection.getHConnection().getTable(Constants.TABLE_CONVERSATION);table.setWriteBufferSize(Constants.HBASE_AUTO_COMMIT);//设置缓冲区,达到大小后提交table.setAutoFlush(false, false);//关闭自动提交} catch (IOException e) {Utils.printStackTrace(e);}

...

Put put = new Put(Bytes.toBytes(rowkey));put.add(family, Bytes.toBytes(key),Bytes.toBytes(value));

...

try {table.put(put);} catch (IOException e) {Utils.printStackTrace(e);}

try {table.flushCommits();} catch (IOException e) {Utils.printStackTrace(e);} finally {try {table.close();} catch (IOException e) {Utils.printStackTrace(e);}}
