Subject Re: help needed towards connecting Hbase
Date Mon, 03 Feb 2014 06:15:29 GMT
Hi,
as directed by Jean-Marc Spaggiari, cleared the file in
 file:////home/hadoop/hbase_temp still i'm not able to create table from my
java code.
as directed by Ted Yu I got the jar from below link added into my build
path.
http://mvnrepository.com/artifact/org.apache.hbase/hbase-server/0.96.1.1-hadoop2
http://mvnrepository.com/artifact/org.apache.hbase/hbase-client/0.96.1.1-hadoop2

Most of the classes definition are not found for the example
I guess with version 0.96.1.1-hadoop most of the client program changed
Trying with this basic program..
package pack1;

import java.io.IOException;

import org.apache.hadoop.conf.Configuration;

import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.util.Bytes;

public class testDB {

/**
 * @param args
 */
public static void main(String[] args) {
try {
System.out.println("1 Before HBASE COnfiguration");
Configuration config = HBaseConfiguration.create();
//config.clear();
System.out.println("2 Before HBASE COnfiguration");
//config.addResource(new Path("conf/hbase-site.xml"));
//System.setProperty("java.net.preferIPv4Stack" , "true");
config.set("hbase.master", "192.168.1.42:60010");
config.set("hbase.zookeeper.quorum", "192.168.1.42");
//config.set("hbase.zookeeper.property.clientPort","2181");
 //HBaseAdmin.checkHBaseAvailable(config);
System.out.println("HBase is running!");
        HTable table = new HTable(config, "test4");
        System.out.println("Table mytable obtained ");
        Put put = new Put(Bytes.toBytes("row1"));

put.add(Bytes.toBytes("colfam1"),Bytes.toBytes("qual1"),Bytes.toBytes("val1"));

put.add(Bytes.toBytes("colfam1"),Bytes.toBytes("qual2"),Bytes.toBytes("val2"));
        table.put(put);
           // table.close();

} catch (Exception e) {
 e.printStackTrace();
}

}

}
