解决：

在createtable函数中加入这两句

HTableDescriptor htd = new ~~HTableDescriptor~~(tablename) ;

HColumnDescriptor col = new HColumnDescriptor( "content" );

htd.addFamily(col);

Configuration cfg = HBaseConfiguration.create();

cfg.set("hbase.zookeeper.quorum","10.254.188.102, 10.254.188.103, 10.254.188.104");

cfg.set("hbase.zookeeper.property.clientPort","2181");

解决：

设置hbase.zookeeper.quorum和hbase.zookeeper.property.clientPort

Configuration conf = new Configuration();

conf.set( TableOutputFormat. OUTPUT_TABLE , tablename);

conf.set("hbase.zookeeper.quorum" , "10.254.188.102,10.254.188.103,10.254.188.104");

conf.set("hbase.zookeeper.property.clientPort" , "2181");//9091

错误3：

hbase windowns 下, Will not attempt to authenticate using SASL (无法定位登录配置)

 INFO ClientCnxn:966 - Opening socket connection to server namenode/192.168.120.129:2181. Will not attempt to authenticate using SASL (无法定位登录配置)

其实这个信息，并不是Hbase的异常，而是客户端找不到zookeeper的解析地址，由于Hbase是通过hostname解析IP地址的(DNS)，Zookeeper只会返回Hbase的域名，需要客户端通过DNS或本地hosts文件进行解析。
解决办法：
在Linux上，在/etc/hosts文件中添加Hbase Master节点的域名及IP地址映射，
在Windows上，修改C:Windowssystem32etchosts文件，添加Hbase Master节点的域名及IP地址映射。
