What are the different data types in Hadoop?
Hadoop supports several data types, including primitive types like int, long, float, double, and complex types like arrays, maps, and structs.
Can you explain what a struct is in Hadoop?
A struct in Hadoop is a complex data type that allows you to group multiple fields of different types together, similar to a record.
How do arrays work in Hadoop?
Arrays in Hadoop are used to store a fixed-size sequence of elements of the same type, allowing for efficient data processing.
What about maps? How are they different from arrays?
Maps in Hadoop are key-value pairs, allowing for dynamic size and easy access to values based on their keys, unlike arrays which are indexed.
