For this weeks activity, we will practice queries in hive. Please write your answers (queries) for the following two questions:

1. In Hive, please create a table called employees with four columns:
   1. column essn (employee SSN) has type String
   2. column name has type String
   3. column dependents has type map, key is relationship(String), value is dname (dependent name) (String)
   4. column salary (float)

2. In the employees table, for column dependents, for the relationship field, there can be only two values either child or spouse. Please write a query statement in hive to extract all employees child dependents names. In the result, we need to have two columns: essn, name of child dependent.
