Hi@akhtar,

You can use the below code to create table in Hbase.

import java.io.IOException;

import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.HColumnDescriptor;
import org.apache.hadoop.hbase.HTableDescriptor;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.TableName;

import org.apache.hadoop.conf.Configuration;

public class CreateTable1 {

public static void main(String[] args) throws IOException {

Configuration con = HBaseConfiguration.create();
HBaseAdmin admin = new HBaseAdmin(con);
HTableDescriptor tableDescriptor = new
HTableDescriptor(TableName.valueOf("table name"));

tableDescriptor.addFamily(new HColumnDescriptor("data1"));
tableDescriptor.addFamily(new HColumnDescriptor("data2"));
admin.createTable(tableDescriptor);
System.out.println(" Table Created");
  }
}

write this java code inside one file and run the file.

$ javac filename.java
$ java filename

Thank You
