server环境:
在virtualbox里安装了ubuntu，然后装了了hadoop2.7.5,hbase1.3.1，然后hadoop和hbase的环境都配置好了
启动了hbase，然后本机里通过scala访问虚拟机里的hbase时，connection能获取到，但是在执行tableExists时，卡一会后就报超时了，client的代码和server的配置如：
server配置(其中zookeeper用的hbase自己管理的)：
hbase-site.xml
client的代码：
class HbaseUtil {
def GetHbaseConfiguration(ip:String):Unit={
var conf = HBaseConfiguration.create;
//这个是远程hbase的ip地址
conf.set("hbase.zookeeper.quorum",ip)
//conf.set("zookeeper.znode.parent", "/hbase-unsecure")
//2181是hbase里zookeeper的默认端口号
conf.set("hbase.zookeeper.property.clientPort","2181")
println(ip+":habse connention success...")
val tableName = "jndata"
conf.set(TableInputFormat.INPUT_TABLE, tableName)
val con= ConnectionFactory.createConnection(conf)
val hBaseAdmin = con.getAdmin//new HBaseAdmin(conf);
val tn = TableName.valueOf(tableName);
// hBaseAdmin.disableTable(tn)
// println(tableName + " is exist,detele....")
//创建表
if (hBaseAdmin.tableExists(tn)) {
println(tableName + " is exist,....")
}else{
println(tableName + " is not exist,....")
}
}
}
然后server端的zookeeper的log如下：
client端的异常如下：

好多办法都试过了还是不行：
1.server和client的防火墙都关了
2.client的host里也配置了server的ip和hostname
