【工具类】系列三 HBase访问工具类 HBaseUtil

这是对HBase访问的简单封装，主要是Spark executor上使用，就没有注意多线程安全了。若有需要自己优化。

 

直接贴代码：

/**

 * Attention: put/get/del is not thread safe due to use HBase Table interface.

public class HBaseUtil {

    private static final Configuration hbaseConf = HBaseConfiguration.create();

    static {
        hbaseConf.set(ZOOKEEPER_QUORUM, Config.getString(ZOOKEEPER_QUORUM));
        hbaseConf.set(ZOOKEEPER_CLIENT_PORT, Config.getString(ZOOKEEPER_CLIENT_PORT));
    }

    /**

        static Connection CONNECT;

        static {

                // init connection
                CONNECT = ConnectionFactory.createConnection(hbaseConf);
