Java API を使用して hbase に接続しようとしています。
192.168.56.101 でローカルに Hortonworks Sandbox (HDP 2.5) を実行しています。
以下は私のJavaコードです
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 ");
}
}
以下は出力です
Trying to connect...
HBase is running!

ご覧のとおり、スタックしており、「取得したテーブル」が印刷されていません。したがって、テーブルは取得されませんでした。
次の jar を使用しています:
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 また、実行可能なjarを作成し、クラスターで直接実行しようとしました。それでも実行されていません。
