我正在尝试使用java API将其与hbase连接。
我在192.168.56.101本地运行Hortonworks Sandbox（HDP 2.5）。
以下是我的java代码
import java.io.IOException;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.util.Bytes;
public class InsertData{
public static void main(String[] args) throws IOException {
// Instantiating Configuration class
System.out.println("Trying to connect...");
Configuration configuration = HBaseConfiguration.create();
configuration.set("hbase.zookeeper.property.clientPort", "2181");
configuration.set("hbase.zookeeper.quorum", "192.168.56.101");
configuration.set("zookeeper.znode.parent", "/hbase-unsecure");
System.out.println("HBase is running!");
// creating a new table
HTable table = new HTable(configuration, "emp");
System.out.println("Table obtained ");
}
}
以下是输出
Trying to connect...
HBase is running!

正如您所看到的那样，它被卡住了，“获得的表格”没有被打印出来。因此没有获得表格。
我正在使用以下罐子：
1）commons-configuration-1.8.jar
2）commons-lang-2.6.jar
3）commons-logging-1.1.1.jar
4）hadoop-core-1.0.0.jar
5）hbase-0.92.1.jar
6）log4j-1.2.16.jar
7）slf4j-api-1.5.8.jar
8）slf4j-log4j12-1.5.8.jar
9）zookeeper-3.4.3.jar
更新 我还创建了一个可运行的jar并尝试直接在集群上运行它。它还没有运行。
