In HBase, you can delete table using HBase Shell as follows:

hbase(main):002:0> disable 'mytable'

hbase(main):003:0> drop 'mytable'

However, you can also delete table using HBaseAdmin API as follows:

public class AdminDelete {

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

    Configuration conf = HBaseConfiguration.create();

    HBaseAdmin admin = null;

    try{

        admin=new HBaseAdmin(conf);

       }

    catch(Exception e)

       {

        e.printStackTrace();

       }

    if(admin.isTableAvailable("newtable")==true)

    {

    admin.disableTable("newtable");

    admin.deleteTable("newtable");

    System.out.println("Table Deleted");

    }

    else

    {

        System.out.println("NewTable does not exist");

    }

}

}
