Answer / Vijyanand Kumar
1. Schema-aware: DataFrames have a schema associated with them, allowing for type checking and easier error handling. 2. Optimized query execution: DataFrames utilize the Catalyst optimizer for better performance when performing transformations and actions. 3. SQL-like API: DataFrames support a SQL-like API for querying data, making it easier to work with relational data. 4. Integration with Hive: DataFrames can be converted into Hive tables and vice versa, providing seamless integration between Spark and Hive.
