hbase java client无法连接 hbase server

使用如下java代码连接hbae，然后输出hbase其中一个表的记录（输出的代码就不贴出来了）：

Configuration HBASE_CONFIG = new Configuration();
HBASE_CONFIG.set("hbase.zookeeper.quorum", "192.168.2.1");
//        HBASE_CONFIG.set("hbase.zookeeper.property.clientPort", "2181");
Configuration configuration = HBaseConfiguration.create(HBASE_CONFIG);
try {
table = new HTable(configuration,"shorturl");
} catch (IOException e) {
e.printStackTrace();
}

运行，打印以下信息后，等待了很久都没有任何错误信息出现（晚上加班搞，不关机回家，第二天一看还是没有日志输出）：

log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

解决方法：
把机器192.168.2.1的域名添加到文件 /ect/hosts 中：

192.168.2.1 test-192-168-2-1
