Subject Cannot connect to local hbase database
Date Tue, 12 Feb 2013 10:50:20 GMT
I'm trying to connect to my hbase database via java program but I
cannot access my database because I get an error message. I checked
that the database is actually running correctly.

Java program:
public class HBaseDemo {

	public static void main(String[] args )
	{
		try {
		
			HTablePool pool = new HTablePool();
			HTableInterface userTable = pool.getTable("users");
			
			Put p = new Put(Bytes.toBytes("CaptainPicard"));
			p.add( Bytes.toBytes("info"), Bytes.toBytes("name"),
Bytes.toBytes("Jean Luc Picard") );
			p.add( Bytes.toBytes("info"), Bytes.toBytes("email"),
Bytes.toBytes("jlp@startrek.com") );
			p.add( Bytes.toBytes("info"), Bytes.toBytes("password"),
Bytes.toBytes("ncc1701d") );
			userTable.put( p );
			
			Get g = new Get(Bytes.toBytes("CaptainPicard"));
			g.addFamily(Bytes.toBytes("info"));
			
			Result r = userTable.get(g);
			String email    = Bytes.toString( r.getValue(
Bytes.toBytes("info"), Bytes.toBytes("email")) );
			String name     = Bytes.toString( r.getValue(
Bytes.toBytes("info"), Bytes.toBytes("name")) );
			String password = Bytes.toString( r.getValue(
Bytes.toBytes("info"), Bytes.toBytes("password")) );
			System.out.println( "name = " + name + "\npassword = " + password +
"\nemail = " + email );
			userTable.close();
			
		} catch ( Exception e ) {
			e.printStackTrace();
		}
	}
}


This is the output of my program:
