# Introduction In the mystic lands of the East, a revered monastery stood atop a towering mountain, shrouded in the mists of ancient wisdom. Within its hallowed walls resided a revered warrior-monk named Hiro, a master of the sacred art of data manipulation. His unwavering dedication to unlocking the secrets of data had earned him the respect of scholars and monks alike. One day, the monastery's abbot summoned Hiro to his chambers, his face etched with concern. "Hiro, a dire situation has arisen," the abbot began. "Our sacred scrolls, containing the ancient knowledge of our ancestors, have been scattered across the realm. We must recover and organize this invaluable information before it is lost forever." Hiro bowed deeply, his eyes alight with determination. "I shall not fail you, venerable master," he vowed. "With the power of Hadoop and its Table Generating Functions, I shall scour the land and restore order to our ancestral wisdom." The abbot nodded solemnly, placing his trust in Hiro's unwavering resolve. Thus began Hiro's quest to master the Table Generating Functions of Hive, a journey that would test his skills and resolve to their utmost limits.
