我在windows（我的本地）中配置了hadoop和spark，并且在vm（同一台机器）中安装了cloudera，其中包含hbase。
我正在尝试使用sparkstream提取数据并将其放入vm中的hbase中。
有可能这样做吗？
我的尝试：
包hbase
import org.apache.hadoop.hbase.HBaseConfiguration
import org.apache.hadoop.hbase.client.{ConnectionFactory,HBaseAdmin,HTable,Put,Get}
object Connect {
def main(args: Array[String]){
val conf = HBaseConfiguration.create()
val tablename = "Acadgild_spark_Hbase"
val HbaseConf = HBaseConfiguration.create()
HbaseConf.set("hbase.zookeeper.quorum","192.168.117.133")
HbaseConf.set("hbase.zookeeper.property.clientPort","2181")
val connection = ConnectionFactory.createConnection(HbaseConf);
val admin = connection.getAdmin();
val listtables=admin.listTables()
listtables.foreach(println)
}
}错误：

基于此错误，您不能使用
quickstart.cloudera因为网络堆栈正在使用dns尝试访问它，但是外部路由器不知道您的vm。你需要使用
localhost，然后确保vm已正确配置为使用您需要连接的端口。但是，我认为zookeeper正在将主机名返回到您的代码中。因此，您必须在您的操作系统主机上编辑hosts文件以添加行项目。
例如
或者，你可以去公园里逛逛
zookeeper-shell或cloudera manager（在hbase配置中）并编辑quickstart.cloudera返回地址192.168.117.133相反
