To view all tables in HBase, you can use either the HBase Shell or the HBase Java API. Here is the method to view all tables using the HBase Shell:

  1. Open the terminal and run HBase Shell:
hbase shell
  1. Use the following command in HBase Shell to list all tables:
list
  1. Upon executing the above command, a list of all tables existing in HBase will be displayed.

The same functionality can also be achieved using the Java API for HBase. You can write a simple Java program to connect to an HBase cluster and list all tables. Here is an example code:

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.HBaseAdmin;

public class ListTables {
    public static void main(String[] args) {
        Configuration config = HBaseConfiguration.create();
        try {
            HBaseAdmin admin = new HBaseAdmin(config);
            String[] tableNames = admin.listTableNames();
            for (String tableName : tableNames) {
                System.out.println(tableName);
            }
            admin.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

The above is a method to view all tables in HBase using either the HBase Shell or HBase’s Java API. You can choose the method that suits your needs to view all tables in HBase.
